Battery: the battery died long time ago, it got bigger and didn't work, so i got rid of it. Bad SATA cable: because I read this in the past, it might be the problem. How can I diagnose if this is the problem? Some app I can install to help diagnose? Bad cooling: I alread open it and cleaned it in the past. And windows display the CPU usage top at 49%.Īll is panfully slow, a simples zip extract of bootcamp zip files somethings locks and 20-40KB/s. It can gow lower the clock speed but not higher than that. The clock speed never passes 1,18GhZ even with the fans at maximum power with Macfans, which keeps it cool at 40º C (65º C with minimum speed). Installed the Bootcamp 4 (the last version for this Macbook from what I found online, at least installs the drivers for my trackpad and the version 5 don't). I made a clane isntall of Windows 10 without anything more. There are some strange symptoms I would like your help to diagnose. Wasn't the 160GB stock, it was an 500GB upgrade, but i changed it to a brande new Kingston 240GB SSD and was expecting it to fly. It was very slow, i thought it was the hard drive. I had Mac OS installed there, don't remmeber which because I felt it was unsuported and unsafe for that. Whatever, in the RAM I won't mess, it is good enough.

I have already upgraded to 4GB which I think it's maximum. I also have a Macbook 4,1 that brought up from the past. A lot of apps support 10.9 as their minimum version: Firefox, Zoom, the Affinity Suite, etc. But the codecs this adds support for are pretty rare in 2020 anyway.Īnd for whatever reason, app compatibility under Mavericks, while far from great, is much better than Mountain Lion. The one big advantage to Mountain Lion IMO is Perian compatibility-Mountain Lion's QuickTime used an extensible plugin system that allowed other programs (namely Perian) to add support for additional codecs, and Mavericks does not. It also wouldn't surprise me if they were actually working on (and focused on) Yosemite already, and just backported certain features and libraries to Mavericks to hit their yearly release cycle. Truth be told, there just isn't much different between the two releases-Apple was likely focused on getting iOS 7 out the door that year. It's possible the situation was different when Mavericks was new, but not in their final iterations. Both were extremely stable and predictable coming from Catalina, and the only performance difference was in memory-constrained situations, where Mavericks actually came out ahead of Mountain Lion due to the fact it can use memory compression. I could not find any compelling reason to use Mountain Lion over Mavericks. I'd officially decided I was fed up with modern macOS, and I was deciding which version to downgrade to as a daily driver.

Click to expand.I did a lot of side-by-side testing of the final versions of Mountain Lion and Mavericks earlier this year inside of VMs.
