You didn't buy a computer so you could clean caches. But a "cache cleaner" isn't useful for anything. A video editor is useful for making movies. For example, a word processor is useful for writing. Only install software that is useful to you, not (as you imagine) to the computer. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery. Some may cause the browser to crash or otherwise malfunction. Most are safe, and they're easy to get rid of if they don't work. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Plugins for Photoshop and similar programs are an obvious exception to this rule. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.Īs a rule, you should avoid software that changes the way other software works. It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. Above all, avoid any software that purports to change the look and feel of the user interface. such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Incompatibility with third-party software is by far the most common cause of difficulties with system updates. Before installing any Apple update, you must check that all system modifications that you use are compatible. Remove them when they are no longer needed. Don't install such modifications unless they're absolutely necessary. Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Otherwise you have to check yourself on a regular basis. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. If you get an indication that a backup has failed, don't ignore it. In fact, don’t rely exclusively on any single backup method, such as Time Machine. Backing up to a cloud-data service is one way to accomplish this, but don't rely exclusively on such backups. Keep at least one backup off site at all times in case of disaster. A copy of a backup doesn't count as another backup all backups must be made directly from the original data. Make two or more backups of all your files The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software. Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. Never install any third-party software unless you're sure you know how to uninstall it otherwise you may create problems that are very hard to solve. If you can’t remove software in any other way, you’ll have to erase and install OS X. Until you do that, there may be no effect, or unpredictable effects. You will generally have to restart the computer in order to complete an uninstallation. The uninstaller might also be accessed by clicking the Customize button, if there is one.īack up all data before making any changes. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button. While you're waiting for a response, download BrickMyMac.dmg and open it. Finding none there, look on the developer's website, say (That may not be the actual name of the site if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Here are some general guidelines to get you started. You'll have to do your own research to find that information. I never install system modifications myself, and except as stated in this comment, I don't know how to uninstall them. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job. Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. Any third-party software that doesn't install from the App Store or by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
