Disk Read/Write never gets above 20MB/s until I Run BlackMagic.
My late 2012 27” i5, without an SSD got very very slow. Disk Read/Write never gets above 20MB/s with normal computer usage until I Run BlackMagic, when disk is capable of hitting over 80MB/s . CPU use is minimal, ram is free and so is disk space.
Looks like something is throttling the system disk access, so anything i do is painfully slow. Apple System Diagnostics shows no errors with even the most thoroug scan, surface scan prooved no errors and so did fdisk -fy from single user mode. Heck, what else could I do except trying to run it from an external ssd installed system?
Это хороший вопрос?
What is the version of OS you have on your system?

I'm on Mojeve now, but things heve been going downhill since previous versions. I did not pay too much attention to it as I've been mostly using it for leisure and my MBP for work for a couple of years, but I could use the bigger screem now but it appears unusable for any serious task.
