12 Steps to Improving Your Mac's Performance
Pages: 1, 2
7. Install Upgrades Automatically
With Software Update, you can enhance performance and security by configuring your Mac to automatically download and install updates both for the operating system and for critical system components such as AirPort, iPod, and iSight. Of course, not all updates apply to all computers, and Apple will tailor its suggested updates around what you have installed. For the most part, you should always install what Apple suggests for your particular setup because those updates will generally enhance performance and increase security. Updates and upgrades will solve known problems too, such as glitches in a software program or bugs in prior updates, and may even contain updates to drivers or firmware, which are necessary to keep your computer running smoothly.
8. Secure Your Mac
Securing your Mac is just as important as enhancing its performance. It doesn't do any good to clean up, maintain, and organize your Mac if you're going to leave it unlocked for anyone and everyone to drop in without your permission. Don't go to all of the trouble of getting it running efficiently, organizing all of its files and folders, and performing maintenance tasks when you've left a door open to malicious co-workers, uninformed visitors, viruses, spyware, or thieves, all of which can really gunk up (or destroy) your Mac. Protect your Mac by incorporating some simple security measures such as using screen saver passwords and turning on OS X's built-in firewall.
Here are some "must do" things: purchase, install, and configure anti-virus software, understand Safari's security options, let friends use a visitor account if they need to use your Mac, turn on FileVault if necessary, understand encryption and when to use it, and set up a firmware password for really tight security.
9. Back Up Your System
Your Mac came with installation CDs that you can use to restore your system if you ever need to. That's all well and good, but they won't restore your personal data: the fonts you've acquired over the years, your Preferences files, the folders you've created, the music you've downloaded, the movies you've made, your Internet cookies, your Keychain entries, and your mailbox files -- you get the idea. If something happens, you need to have all of that backed up.
It's going to be pretty hard to back up, on your own, every single thing you'll need to recover from a hard drive crash. It'll even be harder to try to keep these backups up to date. If you can afford it, purchase a third-party backup utility to help you; the Mac doesn't come with a dedicated one. Sure, there's Disk Copy, but it's not really a backup program, and it isn't going to really do what you want in the way of backups.
There are lots of programs you can purchase to assist you in backing up regularly, and they range in price. Take a look at the options by visiting www.apple.com. If you want to try to find some freeware to help you back up your data, visit www.versiontracker.com. You never know what you might find!
10. How to Maintain Your Mac Once Degunked
Maintaining you Mac once it's degunked will help it perform better for a longer period of time. There are several things you should do on a regular basis, and I've outlined still more in my book. Knowing when and how often to do them is part of it too. Here are just a few things to keep in mind:
- Maintain your Mac by checking for and repairing file system errors.
- Clean up your Mac by deleting library caches.
- Make sure you are getting software updates.
- Use Disk Utility to verify and repair permissions.
- Use the OS X CD to scan the startup disk for errors and repair them.
- Use Disk First Aid to find repair problems with OS 9.
- Zap the PRAM when strange crashes and errors cannot be explained or repaired.
- Create a new user in case of an emergency situation.
- Learn about good third-party applications that can help you maintain and troubleshoot your Mac.
11. Disable Unnecessary Components
There are many system components that can be tweaked to offer minimal improvements but, when combined, offer noticeable changes. For instance, you can remove extraneous extensions, preferences, or fonts you're not using. These extra files increase boot time and slow down reaction time. Application preferences can be set, too, and applications such as Photoshop or Mail can be made to open faster. You can also get rid of system- intensive desktop images and screen savers, or even reduce the color depth of the desktop for a faster redraw. You can disable Calculate All Size, deactivate Remember Recently Used Items, and disable file sharing if you don't need it. There are lots of tweaks that, although seemingly insignificant when performed separately, really add up to improve your Mac's performance when combined with others.
12. Move to OS X if You Haven't Already (Or if You Have a Hybrid System)
The differences between OS 9 and OS X are complex and many. Because they are so vast, the new technology of OS X has forced Apple to offer a hybrid operating system to get people (and software manufacturers) through the move. For programs that are not yet OS X compatible, OS X offers a Classic environment that kicks in when older programs need to be run. The complex changes to the OS may thus require you to use both operating systems for a while, or at least until software manufacturers catch up with all of the changes Apple has made and you purchase the upgrades.
Using older programs though is not the best choice. Your ultimate goal is (or it should be) to use your Mac the way it should be used, with all programs running smoothly in OS X and with OS X performing as a healthy, happy OS. There are several steps involved in making that move, though, including taking inventory of the software and hardware you use often, purchasing new programs when necessary, and even adding RAM.
Briefly, there are six steps to moving to OS X:
- Take a survey of what software you use that causes Classic to open. If you configure System Preferences so that Classic does not start automatically when you log in, and your Mac warns you before starting Classic, you'll be able to see this easily.
- Take inventory of your hardware. Does your web cam hardware and related software open Classic? If so, save up for an iSight, or see if your hardware manufacturer has an upgraded driver and software. Does your bargain-basement printer open Classic? Same thing there -- look for an updated driver or purchase another printer. That'll teach those manufacturers to keep up when a new version of the OS is released!
- Purchase third-party tools to keep the system running smoothly. Your old OS 9 applications aren't going to do the trick. You can also look for freeware or shareware to optimize performance. Check out www.versiontracker.com for the latest.
- Consider adding RAM. RAM is the single best way to increase the performance on your machine and may, in fact, become necessary after upgrading your applications and hardware drivers and adding new programs.
- Transfer your favorite fonts from OS 9 to OS X, just in case you get a wild hair and want to trash the OS 9 folders some day.
- Gather up any documents, pictures, music, artwork, or movies from your OS 9 folders and move them to your OS X folders. Put them in the appropriate folders, such as Documents, Music, Pictures, and Movies.
Conclusion
The thing is, all computers slow down. They all bog down. The reason is that the day you bring your sparkling new computer home, you start storing stuff on it. Stuff can be pictures, music, videos, email, drivers, spam, and whatever else you have obtained, knowingly or unknowingly. You have to take control and maintain control, and if you do, your Mac will be a happy one!

The SMART / verified appears when I use Disk Utility

Don't do anything this article tells you to do. Most of it is well-intentioned, but wrong.
Derrick, I appreciate your comments about respecting the author, but she is not correct on many statements in her article. Sometimes, you have to tell people they don't know what they are talking about.
Based on her demonstrated level of understanding, I would not trust her with anything techology-related in my business.

CC Cloner and MacJanitor
2004-07-24 07:08:04 mmurray [Reply | View]
Two things missed:
(1) A good way to have a reliable backup available is to purchase a FireWire external drive and download Carbon Copy Cloner. Set CCC make a copy every night while you are asleep. Of course disks crash so its probably good to burn a few CD's as extra backup, store off site etc etc.
If you find your mac won't boot one day you can startup with the Option key down and then boot from the FW drive. Then its time to find your copy of DiskWarrior.
(2) If you mac is turned off or asleep at night you probably should run MacJanitor every now and again.
Someone else with more expertise than me might like to advise if (2) is really necessary.

More specifics are definitely needed
2004-07-23 14:28:49 ctb [Reply | View]
With suggestions like "Maintain your Mac by checking for and repairing file system errors." and "Clean up your Mac by deleting library caches." there needs to be a more distinct suggestion made for users who don't understand what these mean.
For example, if Joli instead said "Maintain your Mac's hard disk by booting from your Mac OS X Install CD and running the Disk Utility on a monthly basis." would have been more specific and helpful. Also using other erroneous terms like "library caches" means nothing to regular end users. There are also many 3rd-party utilities (Cocktail, Font Cache Cleaner) that could be recommended to do these tasks, so that users aren't mucking up their own systems if they aren't familiar with the internals.
Also, when instructing users to clean up "font gunk", telling them which folders the fonts are located in, and what fonts they SHOULD NOT remove from the system, are both equally important. I have seen end users remove Helvetica.dfont from /System/Library/Fonts which then caused an array of strange behavior on their Mac. Same goes for LastResort.dfont, Keyboard.dfont and LucidaGrande.dfont.
This is an article with good intent, but needs to bulk up on the specifics!

Credentials?
2004-07-23 08:24:25 mitchellsmith2 [Reply | View]
As both an OS X and Windows sysadmin, I'm mystified by this author's book, let alone the article. Doesn't MacDevCenter check these people out? What are Jodi's credentials?
Spyware, adware..on a Mac? Sorry Jodi, you must be thinking of Windows NT/2K/XP machines, which get so much of this stuff at work that we're routinely reconfiguring and ghosting several PCs per week.
Font removal? Are you kidding? Checking for corrupt fonts is always a good idea, but that's pretty tough (though not impossible for an experienced user) for a neophyte without some kind of font utility.
Defragging? How Windows can you get? As another poster pointed out, OS X automatically defrags files under many circumstances, so this is almost never necessary.
Jodi, would you PLEASE just stick to writing Windows books, and leave the Mac stuff to those who have the experience and knowledge? There are already several good technical OS X books out there; nobody needs another bad one, particularly one filled with so much misinformation which could lead unsuspecting OS X users to damage their systems.

DAMAGE is DONE!!!
2004-07-23 06:27:11 ronosxspt [Reply | View]
Hi all, the DAMAGE is DONE! The book is written and published. Unless you are willing to spread the word about the misinformation in this book, more users will be sucked into making their MACs run less than optimal for a price of $25.00. I am suspicious of the author's motives. It has been pointed out where the article has it many flaws, but yet she refuses to accept or embrace or inputs. She states, "While highly technical Mac users may not agree with some of my suggestions, I do believe that most Mac users will certainly benefit from them, especially the novices that will be purchasing the book...." Most of the flaws that are pointed out has nothing to do with whether you are an expert or a novice. The question is simply. Is the information correct or incorrect? Is what she saying logical or illogical as it pertains to MACs? Is the information useful or useless? If we deem that the information is incorrect, illogical, or useless, then YOU MUST REJECT IT on PRINCIPLE!
I wonder, is this something Microsoft put her up to do? Microsoft is a nasty company and will do anything to inject confusion into their competitors. What better way then to put out a book with misinformation.
We have all heard of the saying beware of a wolf in sheep clothing. Is this a case of a Microsoft user in Mac clothing?

more experience needed...

I believe that this author doesn't necessarily have the experience with Mac OS X to be posting these types of articles; some of the "pointers" simply aren't apropos to OS X, and some of them are so generic that they the value of posting them in this forum is dubious at best.
I appreciate the author's enthusiasm and especially encourage a "windows expert" to explore other operating systems; however one should really do their homework before giving advice on systems that they aren't that familiar with.
I also thank O'Reilly for letting us know that this *should* have been screened better - hopefully future articles will be.

Anti Viral and PRAM
2004-07-21 11:45:02 peterbrodsky [Reply | View]
In addition to the issues already mentioned, I think there is one big one and one little one that no one has commented on yet. Running anti-virus software on a Mac is in my opinion Gunkifying your Mac. Firstly, it causes your machine to slow down, and depending on what program you're using and how its setup, it can make life a living hell. Also, though, in the 12 years I've used a Mac, not once have I contracted a virus, both because there are so few out there, and because I exercise roughly the same amount of common sense even most newbies poses.
The "zap your PRAM" comment was also a strange one. Does the author know what's stored in the PRAM? This is a questionable practice, especially on desktop machines, and it certainly won't speed things up.

classic applications perform marvelous
2004-07-21 05:07:29 Dr.Michael [Reply | View]
The tip not to use classic applications is useless in my opinion.
Once the classic environment is started my old applications like Photoshop or MS Office have dramatically shorter startup times compared to the OS X versions.
They also perform very well. MS Office 2001 for example is definitely faster than Office X.
Looking at performance I highly recommend to go on using classic applications.

classic applications perform marvelous
2004-07-22 08:46:13 tlaurenzo1 [Reply | View]
I can't speak for the classic apps being faster than the OS X versions (since I came to the Mac "post classic"), but it did always bother me that while classic is running (and not doing anything apparent), the CPU usage increases by 15-20%. Obviously, this is machine dependent, and those of you with new G5's wouldn't care. Those of us with old G4's though can't afford for a background process to hog that much processor time. -
classic applications perform marvelous
2004-07-23 07:52:00 Dr.Michael [Reply | View]
I cannot confirm that classic constantly consumes cpu power.
If you do not run applications (exept a cpu monitor) and let the hands from your keyboard my cpu usage goes down to only a few percent with classic running.
The only flaw I found is that classic sometimes (very rarely) hangs and then consumes 100% of cpu. This is surely a bug.

classic applications perform marvelous
2004-07-23 05:26:03 ronosxspt [Reply | View]
Have you checked out Itunes lately. It runs in the background and will normally consume about 10 to 15 percent without blinking. Turn on the visualizer and the CPU jumps to 40 to 50 percent without winking. This is all done in the background. I run with Mac OSX G4 1GHz processor and I don't really notice a hit in performance until CPU usage is roughly 80-90 percent. If you using something, then expect to pay for it in CPU usage. Classic will cost CPU usage to rise, itunes will cause CPU usage to rise, so will Safari and every other program. The question is do you want to pay the CPU cost for what you are doing? If not, then do run the program.
10% CPU usage for an application depending on what it is doing maybe quite reasonable. You need to look at the functionality of the application with respect to CPU usage. Don't say hey my CPU usage has increased by 10-15% for this application and therefore my CPU is being hogged. This is just not true since you are the one deciding to pay for the cost of using the program. Nothing is for free in this starved CPU environment.
The biggest hog on CPU usage that I am aware of is Applescript. If you run an Applescript for a long task, i.e for several minutes, then Applescript will consume 70-80% of the entire CPU resource. Now this is a CPU hog in my book! But I will happily pay the CPU price since I am automating a process and it frees up my time to do something else.

While highly technical Mac users may not agree with some of my suggestions, I do believe that most Mac users will certainly benefit from them, especially the novices that will be purchasing the book. It makes perfect sense to make sure you're getting updates, that your computer is secure, that your files are organized, and that you have a backup strategy. It's also true that the computer will perform better, folders, files, and programs will open faster, and you'll be able to work smarter and faster if your computer isn't gunked up with unnecessary programs, fonts, and other data. You shouldn't have to wade through stuff you don't need to find what you do, and neither should your computer. I believe this is good advice for anyone, and I believe (and through my experiences and others') that it works.
About fragmentation, Apple has this to say about it: "If your disks are almost full, and you often modify or create large files (such as editing video, but see the Tip below if you use iMovie and Mac OS X Panther), there's a chance they could be fragmented. In this case, you might benefit from defragmentation, which might be performed with third-party disk utilities."
I'll agree with some of the commenters that perhaps I stretched that a bit, by encouraging all users to defragment their drives, and perhaps defragmenting is not the best advice for
everyone and every situation. I do appreciate those of you who have brought this to my attention though, and I will certainly put some more research into it. As we all know by now, though, fragmentation is a volatile subject, and a source of contention even at sites I trust the most, like Experts Exchange, and everyone has an
opinion.

About fragmentation, Apple has this to say about it: ...
Yes, but before saying that about it, the very Knowledge Base Article you quote also says things like these:
- "You probably won't need to optimize at all if you use Mac OS X."
- "Optimizing them is a major effort for very little practical gain."
- "There is also a chance that one of the files placed in the "hot band" for rapid reads during system startup might be moved during defragmentation, which would actually decrease performance."

The thing is
2004-07-20 02:15:34 look_to_windward [Reply | View]
I'm sorry, but this article just doesn't make sense in several places.
The thing is, all computers slow down....Stuff can be pictures, music, videos, email, drivers, spam, and whatever else you have obtained, knowingly or unknowingly.
This is quite clearly untrue. Storing 'stuff' on your computer will in no way slow it down, so long as you don't approach the limit of the hard disk (and thus possibly impact paging memory to disk). This is a common misconception among users who don't know the difference between RAM and hard disk space, and this author is encouraging the confusion by repeating this falsehood several times in the article.
1.Throw Away Data You No Longer Need and Defragment Your Drive
What difference will throwing some documents away make? It may clear up disk space, but it most certainly won't increase performance. Defragmentation is no longer required in Panther, but the author makes no mention of that. As to 'two to four times a year' - pheh.
2. As mentioned in the previous section, when you reduce clutter, you improve the performance of your system.
Once again, this is repeated - would the author care to explain why this is the case? Removing applications will NOT improve your system's performance. If you don't run as many applications all at the same time, you might impact performance.
6. Get Rid of Font Gunk
This is very dangerous advice for people who aren't sure what they're doing - which I assume is the target audience. Most of those people are unlikely to have a lot of fonts on their system anyway. While removing fonts can speed up various applications, it can also break the system in subtle ways. A list of essential fonts would be good, and I'd leave out the advice to remove 'bold, italic versions'. This advice is a recipe for disaster and won't significantly impact system performance.
I won't go on, but this article has some serious flaws, in particular the vague summary which implies that anything copied to a computer's hard disk will slow it down. The best advice they could give anyone who wants more performance under OS X is to buy more RAM; as much as they can.

C'mon guys, you've made your point. No need to beat on this article or author anymore.
I'd like to give you a bit of background here. Joli Ballew comes to Mac DevCenter by way of our publishing agreement with Paraglyph Press. They produce some pretty good books, but don't have the web sites, distribution contacts, etc. that O'Reilly has.
I just checked Amazon, and the book, Degunking Your Mac has a four star review with 5 out of 6 agreeing with it. So, it's not out of the ballpark here, right? The article has a few points that need clarification that we can handle in the TalkBacks.
Now I know this isn't standard Mac DevCenter fare. And it's my fault for not giving you a heads up in an Editor's Note about the content to follow. My bad, OK?
So let's ease up on Joli a bit, stay constructive, and help make the TalkBacks useful by clarifying the article.

If "some of the opinions are a bit strong in their phrasing", it is because most of us have come to believe in the equation of my subject line. And having this article being published by O'Reilly seems to violate that equation.

Defrag not necessary on OS X Panther
2004-07-17 10:40:10 kelleherk [Reply | View]
it seems this article was written for generic, even OS 9 and pre Panther OS Macs. I think the suggestions here are making more work for you than you need to worry about.
For example Step 1 defrag is not necessary in Panther since when a file is opened, if it is highly fragmented (ie. 8+ fragments) and the file is under 20MB in size, it will be automatically defragmented. This is accomplished by the file system just moving the file to a new location. This process only happens on Journaled HFS+ volumes which is default on Panther.
For Panther, keeping it running smooth and quick is easy.
When you sense the slowdown, do the following
1) Dump the data files you don't need and try to keep 10GB free on your drive to give the virtual memory swap files elbow room.
2) Set up a cron script once a week to repair permissions automatically
3) Use Cocktail to force prebinding the entire system every 3 months.
4) Restart your OS Panther machine at least once every three months.
5) Put as much memory as you possibly can into your OS X Mac.
