I've also seen others with other Macs post similar issues w/10.10.3.
10.10.3 has graphics issues, causes my Mac to lockup or overheat and shut itself off sometimes, and that's not happened with this Mac before. 10.10 has been faster than all the rest, similar to or faster than 10.6.8, but, buggy. I will do, mostly because many have done it with no issues, and I don't have to do the hack myself.oh, although, I did create my own Fusion drive, but, that's enough for me.)Įven so, I do understand sticking with 10.6.8.I recall it being the most stable and fastest OS X ever.
(Even though I do have a BT4 USB dongle, and used continuity activation tool to utilize handoff & continuity. And that is what I think I recall about 10.7.5, 64-bit was more fully utilized across the OS, and with Core2Duo CPUs. RAM for these Macs at 8GB, because, even if more could be installed, at that time, it could not be fully used, so, rather than Apple explain the limitations, they simply stated you could not put more than 8GB in these machines, for, if they had let people build it with 16GB RAM, and later they found the RAM was not being utilized, people would complain.Ĭlick to expand.When I was trying to find the issue, I did see the 4GB thing, now I get it, so, yes, the Mac sees 16GB, but, if you use an app that could use more than 4GB, it won't be able to.Īs far as the 64-bit mod., yeah, I can see that helping, but, I, personally, wouldn't do it. These Macs came with 10.6.3, and, at that time, Apple stated the Max. I'm also not sure if it was that, while the Core2Duos were 64bit, the OS was not fully 64bit yet, and that's where the issue was. And I'm not sure if it only utilized up to 8GB or 12GB.
(I can see how much free RAM I have in my menu bar with Memory Clean app, free on Mac app store.)Īctivity Monitor might show all of your RAM in your Mac, since that hardware is there and the Mac sees the hardware, but, the OS is not utilizing all of the RAM.there are limitations in Snow Leopard (and older) that were released in 10.7.5, but, I can't remember the specifics, and I can't find the information from quite a while back. It will go below 8GB when using Aperture, or multiple apps open. I find my Mac will use all the RAM with Time Machine backups or even running permissions repair in Disk Utility.
