Tuning Mac OS X Performance

Tuning Mac OS X Performance
This FAQ provides recommendations for optimizing Mac® OS X performance. Additionally, it provides advice and links to advice for troubleshooting certain Mac OS X performance problems. Comprehensive advice on this topic can be found in the "Performance" chapter of our book Troubleshooting Mac OS X. Optimizing Mac OS X performance RAM, RAM, and more RAM Mac OS X loves RAM. Maintain ample free space on your startup disk Mac OS X makes extensive use of Virtual Memory (VM), which requires free disk space on your startup disk, aka your boot volume. See our "Problems from insufficient RAM and free hard disk space" FAQ to determine if you have sufficient RAM and free disk space to get the best performance from Mac OS X. Turn off the eye candy While I imagine everyone is impressed the first time they see a window minimized to the Dock with the Genie effect, this entertainment has a performance cost.

Must-Have Mac Maintenance Apps According to Murphy's law, anything that can go wrong will go wrong. This holds especially true for mechanical and electronic devices. If you don't change your car's motor oil, your engine will eventually seize up. And if you don't perform regularly scheduled maintenance on your Mac, your computer could be in a world of hurt. Forcing Background Maintenance Tasks According to Apple, every Mac running Mac OS X is supposed to perform maintenance tasks in the background. Mac OS X periodically runs background tasks that, in part, remove system files that are no longer needed. You could just leave your Mac turned on every night. We'll show you how to do that with a third-party application. Oh, and in case you're interested, you can manually force the background maintenance tasks to run by typing some commands into the Terminal.

Problems from insufficient RAM and free hard disk space If you have a limited amount of either RAM (memory) or available — free or unused — space on your Mac® OS X startup disk, you may encounter problems including kernel panics, the inability to burn CDs or DVDs, or the apparent loss of application preferences. This FAQ, which is derived from a chapter from our book Troubleshooting Mac OS X, describes the basis of these problems and solutions for such. Memory management in Mac OS X Applications and processing on your Mac require physical RAM to work. The more applications you launch or the larger the files those applications work upon, the more physical RAM is consumed. To efficiently use your available RAM, Mac OS X employs a strategy common to all modern operation systems known as Virtual Memory (VM). Paging is a key activity of VM. To free RAM for other applications and processing, data is copied from RAM to a swap file. Swap files are created and released dynamically and are saved in the /private/var/vm directory.

Hands On: Easy Mac Maintenance | Software Just like your car, your Mac needs routine maintenance in order to run smoothly. Unlike your car, your Mac can perform some of this maintenance on its own. Two important tasks to perform regularly are Disk Utility's Repair Permissions and OS X's Unix maintenance scripts. Repair Permissions ensures that system-level files have the correct privileges set; this is important because incorrect permissions can prevent applications from launching, cause problems with printing, and even affect startup. You should occasionally run Repair Permissions and the maintenance scripts when you boot your Mac into OS X. Schedule Repair Permissions 1. To automate an action with cron, you need to open a crontab (a cron table, or schedule) and then create a new entry -- much as you'd create a repeating calendar appointment -- that tells cron what to do and when. CronniX gives you an easy-to-use interface for working with crontabs. I run Repair Permissions once a week, Friday mornings at 10:15 a.m. 2. 1. 2. 3.

Resetting your Mac's PRAM and NVRAM Languages Learn about your Mac's PRAM or NVRAM, and when and how you might want to reset it. Your Mac stores certain settings in a special memory area even if it is turned off. Information stored in NVRAM / PRAM includes: Speaker volume Screen resolution Startup disk selection Recent kernel panic information, if any If you experience issues related to these functions, you may need to reset the NVRAM or PRAM. Note: OS X does not store network settings in NVRAM / PRAM. Shut down your Mac. After resetting NVRAM or PRAM, you may need to reconfigure your settings for speaker volume, screen resolution, startup disk selection, and time zone information. Resetting NVRAM in Open Firmware If your computer is Open Firmware-based and you are unable to reset NVRAM as described above, you may alternatively reset the NVRAM and Open Firmware settings using the steps in the Solution section of Message “To continue booting, type 'mac-boot' and press return”. Some earlier Macs store these settings in PRAM:

Essential Mac Maintenance: Rev up Your Routines - PCWorld Macs are relatively hassle-free--most people can get by without doing any routine maintenance at all. But you can greatly reduce your chances of problems, both big and small, by regularly performing a few simple tasks. I recommend performing some--such as backing up your data--diligently and often. Others require your attention only occasionally. Wondering how you'll remember what to do when? Back up your data There are two types of people: those who've lost data and those who will. Leopard's built-in backup system, Time Machine, makes it very easy to keep copies of your work. For more information about how and why you might combine Time Machine with other backup methods, see "Is Time Machine all you need?". How Often How much work can you afford to lose? Keep software up to date Why suffer from bugs that have already been fixed or security issues that have already been patched? Schedule Apple Updates Keeping OS X and other Apple software up-to-date is easy. One caveat is in order here.

7 Tools to keep your Mac Healthy For the four years I’ve been using a Mac, I haven’t used a maintenance tool. All I’ve ever done was verify disk permissions, and maybe use Drive Genius to perform some optimisation. But even that was just something ‘extra’ and not necessary according to me.
