If your Mac looks retarded and holds at from time to time, perform the following fixes to work around th is sue:
REBOOT THE MACBOOK
In case a reboot cures the issue, and the problem is not returning, your troubleshooting work is done.
ANALYZE AND FIX THE CATALOGS
LOOK AT THE FILESYSTEM AND FIX ALLMISTAKES, THROUG DOING THE FOLLOWING:
• Load your Mac from the OS X Boot CD
• Activate drive Utility and choose ”repair disk” option
In case there is no access to the OSX install Optical Disc, apply the UNIX-based request fsck using Terminal set up for in Single User Mode. That specific way of performing that differs due to the version of MacOS you are using. Go to Apple Support for specific guidance. Drive Utility will do an analysis of existing fixes, and solutions that took place. If drive Utility is unable to fix a inconvenience, you need to get a third-party utility, or reformat the disk prior to starting any other actions. Sure thing - format of your disk must be your last resort, since that action must clear the hard disk. Try a third-party utility before that; if that does not work, do a thorough backup of all your data (including loaded programs and personal settings), before doing a disk format.
ANALYZE CAPACITY ON YOUR SYSTEM DISK
You should possess at least 0.5 GB of unused space at any moment. Keep in mind the fact that even in case there is larger amount of free space than the amount this when you first Boot, auxiliary files may decrease disk space swiftly. Therefore, it would be a good approach to store at least 3072 Mb of free space immediately past Booting.
To solve this problem put to Recycle Bin unneeded information as well as applications stored in System volume to clean free capacity. You can also, try to set – up fewer swap - files by adding more memory or running less applications at the same time. Reloading will temporarily remove all swap-files, but they will come back.
REPAIR PERMISSIONS
Run this in disk “utility” in your general user login. Choose Boot drive and activate ”first aid” tab, and after that click the “repair permission selection. Learn In case that cures the problem.
FREE OS AND USER CACHE FOLDERS
Use a external developer tool similar to “Onyx” or Cocktail to thoroughly deep clear every cache folder, after which reboot. See if this cures the issue.
UNPLUG ALL USB OR FIREWIRE GADGETS NOT COUNTING MAC’S MOUSE
Reboot your Mac after unplugging all hardware. If the action makes the problem fade away, the reason is probably that you have a bad external hardware, bad cable, or unreliable port on your computer. Find out isolate which one it is. Be especially wary of USB ports.
Dashboard’s Widgets
One of those backgrounds for issues with a Macbook work is that you have too many active Dashboard Widgets. Those are very nice in reducing available operative memory. That is why you must check that list of already active Widgets and shut down those that are taking too many resources. The single way to solve that problem is possibly to shut them down one by one till your system starts working properly.
Problems with font
Another common issue that must be solved when a Mac freezes is removing unused fonts. The reason is that average Mac is programmed to load all the fonts with no regard to whether they are used or not. Disable those fonts which are no longer necessary and this way improve the Mac performance.
