Over time we all build up lots of files, photos and videos that we seldom use. The lesson here is to make sure you have as much free space as possible, and possibly archive your old files to an external disk, a cloud service, compress them or simply delete stuff that you don’t need anymore. Once you’ve installed lots of new apps, disk space can quickly be eaten up, and the more files you have the longer it can take to find files, index them (for Spotlight searches) and defragment them (which is done automatically by OS X).
Do you have enough disk space for applications, movies, photos, the OS X and more…? It’s even worse if you’re low on memory too, because your computer may not have enough disk space to use as virtual memory, thus compounding the problem. It’s much more cost-effective to upgrade memory once you’ve bought your Mac, but note that the new Retina Display models cannot be upgraded because the memory is soldered onto the motherboard and cannot be removed.Īpple states that 8 GB of disk space is needed to install Mountain Lion, however if you’re running out of space then you might notice a significant slowdown in the general performance of your Mac.
One last tip – don’t buy memory modules from Apple because their prices are extortionate compared with companies like Crucial. Insufficient memory will cause your Mac to use “virtual memory” on the disk which is slowĪ lack of RAM isn’t limited to Mountain Lion only – whatever version of OS X you’re running, it’s advisable to install as much memory as possible as an after-market upgrade, or worst case buy your new Mac with lots of RAM to begin with. Memory upgrades are surprisingly easy to do and mean that your Mac won’t need to use hard disk space as “virtual memory”, thus ensuring everything is running optimally and speedily. RAM prices are now as cheap as chips, so 4GB should be the absolute minimum to have installed – however 8 GB or even 16 GB (on the newer Retina Display Macs) is definitely recommended if you can afford it.
