I have been working to get AHCI working on my Catalina installation. I tried installing AppleAHCIPort.kext to \L\E\ and then tried SATA-unsupported.kext to \S\L\E\ as recommended in several posts. I used KextBeast to install them. I also added some AHCI patches along with the kexts. The...

This has been an intermittent problem for me since I updated from Chimera+Yosemite to Clover+Catalina. This update has caused all sorts of problems (learning Clover, unsupported hardware, etc) for me, which I have now mostly worked out. I still get sometimes freezes running Catalina on my SSD...

It took a while to get keyboard at the OC picker. Now I get to the Catalina login screen but have no USB function (so no keyboard to log in). It seems that USBInjectAll, and XHCI-unsupported may not be working? USB works in BIOS and at OC picker, but not at Catalina. I have tried everything I...

I think this is 'basic' stuff, but for some reason(s) I am not able to successfully install a working Clover to a USB drive. I have a long history of problems that I am trying to work through - but I will try to spare the unnecessary details here. I have two versions of a USB Clover v5127 (Call...

Old Thread Title: Old/Legacy Sandy Bridge Catalina - Help with Beachballs, HDD lag, hang/pauses Background I have an old sandy bridge machine that I have installed Catalina on using MultiBeast and Clover. I updated from Yosemite at the same time I updated to Clover for the first time, and...

I have an old SandyBridge hackintosh (in sig) that I have Catalina running on. When I last updated it (from Yosemite to Catalina), my Samsung SSD started causing freezes. I had other HD issues (occasionally partitions would start throwing I/O errors, needing a reboot). I abandoned my SSD in...

I have been chasing several problems after my recent upgrade from Yosemite/Chimera to Catalina/Clover. I have slowly traced persistent fan speed/noise problems, to what I think is a power management problem, that may be causing other problems, including random freezes (on SSD only), and no wake...

Sometimes when I boot up my Catalina build, I cannot write to any internal HFS+ partitions. I get an error "This operation cannot be completed, Error -50." I cannot find anything online about this error. Most of the time when I boot up my Catalina build, the disks work correctly and I can...

One of several remaining issues on my hackintosh to fix is getting my main system going on my Samsung 850 Pro SSD. I am currently running Catalina on a partition on a larger non-SSD drive, and it is generally working. However, no matter what I do, any installation on my SSD experience random...

I recently upgraded my Chimera/Yosemite hackintosh to a clean-install of Mojave, with Clover. I also changed out my GPU for RX 560 because my old Radeon is no longer compatible. At first, I though the RX 560 fan was the problem, as this seemed to be the main "change." Once I finally got my...

I tried posting something similar a few days ago and I think it said "pending moderator approval" or something. I cannot find it, and it's been a few days, so here it is again: I recently upgraded from an old Chimera/Yosemite machine to Clover/Mojave, and have been having problems getting...

I have my hackintosh running pretty well, and am trying to resolve a few more issues. Ever since the very first installation of Mojave on my system, I get a CMOS Checksum Error after every boot, erasing the BIOS. While I am still able to restore recent backup BIOS and boot without an issue, I'd...

Sorry for such a long post, but I think most of this history is relevant. Thanks for your help. I have a working Yosemite installation (using Chimera) and am trying to update my system to Mojave (for now), and beyond. I have several partitions used for OSX: Main HD (SSD) - Yosemite, Chimera...

I'm really frustrated, and not sure where to turn next. I had a working Yosemite installation using Chimera, but the system would only boot about 1/2 of the time. The other half would KP on AppleIntelCPUPowerManagement. I have a GA-P67A-UD4-B3 using F8 bios. This board has a backup BIOS (which...

I have a working Yosemite installation using Chimera. I am starting to test upgrading to Clover, then to High Sierra, and replacing my Gfx card with an RX 560... I have made a Clover USB stick (Legacy, with config.plist standard) to test with, which successfully boots my primary drive. I have an...

I'm starting to move towards updating OSX on my older (only) machine from Yosemite. I think I can update to Sierra, not sure beyond that. I'm also looking to upgrade my monitor (and therefore my graphics card) to 4K. I don't need high performance for gaming, but I do 3d graphics and rendering...

About this Mac and System Profiler both report RAM speed at 0 MHz. Another site recommended running "sysctl hw.busfrequency hw.physmem" in terminal to check the bus speed, which results in 100 MHz. Since installing Yosemite, I have had reduced performance (random system hangs, beach balls...

SSD with Mavericks and admin account Larger HDDs with my user account (home), storage and clone backups I'll post more as needed, but am on iPad since hackintosh won't boot so want to minimize typing. Periodically, (2 or 3 times in last 18 mos) my computer would unexplicitibly crash while I...

I have a SSD as my primary OSX boot drive in my Hack desktop that has failed. It started with intermittent freezing, which upon reboot didn't always recognize the SSD. Now the SSD is never recognized and I am unable to boot at all. I have a clone backup on a partition of a different disk in the...

I need some help troublshooting this intermittent problem. Two days in a row now, I get home from work, power-up the hackintosh and first, my bluetooth keyboard won't work to login (its a Microsoft Keyboard w/ USB bluetooth dongle). I reboot. 2nd time, the keyboard works, but I get no...
