ML 10.8.4 on Dell Optiplex 755 - slow sata


Recommended Posts

I installed ML 10.8.4 on a Dell Optiplex 755. While installation went smoothly, disk r/w speeds are very bad.


Any clues how to start troubleshooting this ?


System information lists ICH10 AHCI , 1.5 gb/s link speed negotiated, AHCI 1.20 supported

I wouldn't judge the performance of a Hackintosh on the basis of these Benchmark tools. Don't rely on them. Are you using SSD or standard HDD? If HDD, what speed?


Check your HDD BIOS mode settings too. ideally set it to AHCI or RAID.
