    ATI Radeon 5870 for Photoshop on High Sierra

    Hi. I have just installed High Sierra on my 2008 Mac Pro 3,1. Everything works fine, except Photoshop CC gives me a message saying I need at least 512mb of VRAM to render Flame, Picture Frame, Tree and 3D. I am using an ATI Radeon 5870 GPU. This card has 1GB of RAM, so I don't understand why...

    Adobe Premiere hardware acceleration not working on Mojave after patcher update from High Sierra...

    I'm pretty sure before I updated to Mojave from High Sierra on my 2011 Macbook Pro (8,1) I had hardware GPU acceleration working in Adobe Premiere. I'm assuming this is an effect of having to patch the video card drivers in the Mojave patcher, though I could just be misremembering it from also...

    Mac Pro 3,1 not booting after High Sierra Patcher

    Hi everyone. I'm new here. I have just installed dosdude1's High Sierra Patcher on my 2008 Mac Pro 3,1. The Patcher installed fine, I managed to run the installer, then that completed and went to reboot (as it should have). My issue is that now the machine seems to try to boot up, but shuts off...

    Anybody running iTunes 10.7 on High Sierra?

    I never gave up on iTunes 10.7 and got it to work on Yosemite, El Capitan, Sierra and High Sierra without losing Mac App Store’s (MAS) functionality. Might also work on Mojave (but I haven’t tested it yet). Here are the steps I follow to revert iTunes 12 to 10.7...

    SSD installed on 2011 iMac. Sierra runs great...but HighSierra?

    I had El Capitan on this iMac what felt like forever. The HD was showing signs of failure about a month ago (SLOOOOW boot up, mouse stuttering, erratic behavior, "chugging" of the HD.) I backed everything up, installed the SSD. No problem, it feels great now. I then took the dive and clean...

    Installing Windows 7 on Mid-2011 iMac

    Hi folks! I recently replaced my 2011 iMac's failing internal hard drive with a nice, spacious 4TB chonker, and decided I could spare the room for a Windows partition again — it's been a few years, and there are a few Windows-only games I wouldn't mind trying to play again. Thing is, my iMac...

    WiFi cutting out repeatedly

    Noticed recently that at times, fairly frequently, that my wifi on my MacBook Pro would cut out. By cut out I mean the signal is still active, by all indications it is still connected but there is no upload/download network activity happening. The odd thing to me is that simply by clicking the...

    Missing volume after updating to High Sierra

    I've got an old MacBook (Mid 2010) with a physical HDD containing 3 volumes - each is a boot volume and all use FileVault2. Under Sierra all of the volumes were visible in Disk Utility and in the Startup Disk System Preferences. After updating from 10.12.6 to 10.13.6 one of the volumes is no...

    Mojave TM on High Sierra shared drive?

    Hey all, I’ve reurposed my old 2011 MBP as a home “server” to run iTunes etc, and it’d also be nice if I could use it to share a drive for a Time Machine network share. I’ve tried sharing both a whole disk and a folder on it, with the TM option set in the shares “advanced” dialog, and tried...

    cMP 5,1 does not shut down

    My cMP 5,1 (flashed 4,1) running High Sierra does not fully shut down. The screen darkens but the cursor stays on. When the screen darkens, cursor jumps to upper left corner and remains live. If left alone, it seems system or monitor will sleep and awaken when mouse is moved. Just started...

    Hello MacRumors, Ran into an issue yesterday after installing High Sierra onto my 5,1. I upgraded my 5,1 to HS as a part of my journey to Mojave, installation was fine and easy. My machine was previously running Sierra and Windows 10 on separate SSDs and I was able to switch back and forth...

    Mac Pro 2009 GPU upgrade issues (RX480)

    Hey everyone, first post here. I recently acquired a 2009 Mac Pro (4,1 flashed to 5,1) successfully updated to High Sierra. I had an ASUS Dual OC RX 480 lying around and am having some trouble getting it running properly. As far as I've researched, High Sierra is supposed to have built-in...

    I have a flashed 2009 Mac Pro which had already been running High Sierra from an SSD without problem. I want to install on an external drive (eSATA). The drive previously was bootable on this machine and contained Mountain Lion, which I erased. It seems that no matter how I try to put High...

    Flashed Mac Pro 5,1 strange High Sierra upgrade phenemenon

    I have a flashed to 5,1 '09 Mac Pro that had been happily running all OSs up to Yosemite and then Sierra on an OWC SSD, for maybe 4 years. A little while ago I re-flashed with a newer version that was said (on a forum devoted to the flashing process) to be necessary for High Sierra, and Sierra...

    High Sierra installer?

    Where can I get the High Sierra installer, or other previous OSs? I have an older flashed Mac with a problem boot drive and I need to do an install on a new drive. The recovery partition isn't working. I have El Capitan and Mountain Lion installers on my system, no Sierra or High Sierra.

    MacBook Pro failure or SSD failure?

    Hi, The other day I upgraded my MacBook Pro 2011 (with an SSD) from Yosemite to High Sierra, it rendered it unusable. I attempted to do a clean install but it kept falling or stopping. I've now reinstalled Snow Leopard from the DVD that came with the MacBook (this took 17hrs). Again it's...

    PCIe SSD boot problem

    Hi, I’ve recently upgraded the processors and graphics card in my Mac Pro and everything was working fine using OS Mojave. To speed things up I added a PCIe SSD Card and cloned it (Carbon Copy Cloner) from my existing bootable drive. I then set it to be my startup drive. Seems that this was a...
