Chosen Solution
Hello everyone! I encountered with problem and I have absolutely no idea how to resolve it. I have an iMac mid 2011 27" with core i5-2400 (3100MHz) radeon 6970-1gb HDD 1TB . https://s31.postimg.org/jnregi8ob/Screen…
My HDD had broken, so i decided to install SDD instead of it. So I replaced old hard disk and put ssd Crucial MX200 500Gb instead. I installed Mac OS 10.7 from scratch using embedded recovery system, and after what updated to 10.11.5. Everything was fine until I decided pass some benchmarks. And all benchmarks show that cpu results only a half of expected. E.g Cinebench R15 https://s31.postimg.org/z28vmj2bf/Screen…
I tried to figure out what the problem and install Intel Power Gadget utility. It reveals next - CPU frequency does not rise higher than 1600MHz even in 100% cpu load tasks. It freeze on 1.60GHz a not move even a bit. The line on the graph is absolutely flat! https://s32.postimg.org/npa8t9bhx/Screen…
And there are no CPU overheat as all! Temperature not raises more than 50C degrees. And GPU also work at ~20% of it power according to benchmarks (two times less points than ge-force 620m has). I have no idea how to resolve this issue. Please share your experience in such cases
First take it in to an ASP and have it tested for this free repair program: https://support.apple.com/en-us/HT203787
The older MacBook models with user removable batteries were rigged to run on half clock speed whenever they were run with the battery removed from the device and with ac power. I guess something could have triggered your macOS into thinking that you “battery is removed”…
