Instead, manually copy all your documents across and reinstall your apps from the App Store or CD-omitting those you don’t need.
#Old mac os program install
Usually, a Mac that has slowed further and further down has just accreted apps, files and more, and one of the surest ways of restoring the pep and vigor it had out of the box is to wipe the hard disk, install a fresh OS, and then, crucially, don’t clone everything across using Time Machine or the like. Oh, and never be tempted to install MacKeeper. One good idea is to run Verify Disk in Disk Utilities (/Applications/Utilities) on your main startup disk every now and then to identify problems, and watch the SMART status for your boot drive in Disk Utility too it’s monitoring for signs of imminent failure. These days there’s less need for that, but there’s usually no harm. In the early days of OS X, we regularly repaired permissions and ran apps such as Cocktail or OnyX to clear caches and more to keep the system trim and tidy. (And don’t ever bother with “RAM cleaning” or flushing apps OS X takes care of that for you.) Again, you can sort the RAM chart by Memory to see what apps are demanding RAM consider quitting RAM-hogs if you’re not actively using them. Start using your Mac as you would typically, and if the Memory Pressure graph on recent OSs isn’t looking full, you don’t need more RAM on earlier systems, if the pie chart of RAM use shows mostly green and blue, the amount of RAM you have is “cool” if it’s mostly red and yellow, you’re in hot water, and need to add more.
If you’re trying to run many, complex apps at once, your Mac might struggle. If you don’t recognize a process, Google it it might be a background app that’s run rogue.Īctivity Monitor will also show you pressure on your memory (RAM). This will show you what applications are demanding the most from your main processor (CPU) click the %CPU column header to sort by this, and ensure you’ve selected All Processes from the View menu. So your first diagnostic step is to launch Activity Monitor (/Applications/Utilities) and see where the pinch points are. Like a doctor, you need to understand why your Mac is sluggish before blundering in with treatments.
