This will link it to your AppleID and you will have access to it long after it's no longer supported. On a side note, I suggest "purchasing" (aka downloading) every macOS version that comes out even if you have no plans on using it immediately.
#Make mac run faster yosemite download#
Personally, I have found El Cap to be extremely stable even on older MacBook Pros such as yours.Īlthough Apple has traditionally killed off the ability to download older versions of macOS unless you "purchased" it previously, they have made the El Captain installer available for users with Macs unsupported by Sierra. However, I wouldn't go to Yosemite I would go to El Capitan and be done with it (it's the highest OS supported by your MacBook Pro).
That said, I have personally held off on Sierra because all the perceived benefits it brought are outweighed by the myriad of issues it has (El Cap is still current, so it's not a problem).
Holding on to an old version of an OS can potentially lock you out of important fixes. Beyond any perceived performance enhancements, you need to get security and bug fixes. Worrying about very minute temperature changes of a CPU is academic at best. In large data centers we concern ourselves with heat, but not to the degree (pun intended, maybe) here. If the CPU gets too hot, it will shut itself down. Conversely, if you have lots, it will generate lots of heat. If you have no processes running that consume CPU cycles, it won't generate any heat. The temperature of your CPU/GPU is dependent on how much work it's doing.
Heat is a topic that seems to get way more attention than it deserves. Again, if your app is slow on Mavericks, it will continue to be slow on Yosemite. Any performance gains (speed) will be negligible. Performance? Heat? (I assume you are talking about efficiency here.) You will probably notice increase stability in your apps. If your apps were slow to begin with, they are going to be just as slow with an OS upgrade. Does Yosemite make my system run faster what about performance andįaster? Not that you are going to be significantly notice.
