    Howdy y'all. Long time no see. in 2022 I received a pcie Powermac G5 dual core 2.0 (not dual cpu) because a friend of mine was emptying out some old stuff of his mother's and because he knew I was a macmodding guy he gave it to me. I installed linux on it, played around, compiled a bunch of...

    Where exactly does the leak occur on the PowerMac G5 Quad?

    Recently I finally managed to acquire my dreamed PMG5 Quad, I was aware of the leak problem that usually occurs, my computer seems NEVER to have leaked, but I don't want to start using it without first ensuring that this will not happen. I also know there was a second revision that looks like it...

    Anyone using PCIe SSD cards like Tempo? Any success making those SSD bootable?

    Interested to hear some real-life experiences. Theoretically it should be possible, and at least Tempo are officially supported (bootability is not, but apparently doable via OpenFirmware trickery.) What SSD make sense to get for such cards to get the max speed while not overpaying unnecessarily?

    Help buying a powermac g5 (quad especially), I think I'm searching for the wrong thing?

    Hi, I'm trying to get a powerpc64 computer to run linux on, as I need it to compile my code for a mate (long story), and, to my knowledge, the g5s are basically the only option other than spending a couple hundred quid on a pseries server. I want to get the late 2005 g5 quad, as it's got the...

    Hi, I recently bought a dual 2.5 GHz powermac g5. It was working fine doing stuff on 10.5.8 leopard until i shut it down. Now when I boot to the desktop, it freezes up about 10-15 seconds after reaching the desktop. I tried booting into safe mode but it just boot loops and now I'm stuck boot...

    Power Mac G5 longevity and usability questions

    After having previously purchased 2 of these aluminum monsters, I plan to keep them alive for as long as the hardware will allow me to (and hopefully push them to their limits). That leads to my questions: What should the standard procedure be to keeping these things operating optimally? I...

    Looking for RTL8811CU driver for Powermac G5/10.5

    As the title states, I've been looking for a driver for this specific Realtek chip for my two G5's. I'm unable to find it anywhere and wonder if anyone has a driver that's functional for these adapters for Mac OS 10.5. I would get an airport card if one of the systems I was planning to use it on...

    Saving my 2,5ghz liquid cooled PowerMac G5

    Hi community, so I have my old PowerMac G5 Late 2005 with 2,5 ghz dual cpu single Delphi pump laying around, but it’s broken. It immediately overheats, which makes me suspect the pump. That LCS is just unusable for me and I am not experienced enough to bother fixing it. So I searched on eBay and...

    PowerMac G5 AIO Mounting Bracket

    Hello, This topic stemmed from an idea I had to potentially improve and or experiment with the cooling inside my Late 05 2.3Ghz G5. The concept was simple, I wanted to develop and design a 3D printable AIO mounting bracket for a Corsair H60 Original model AIO cooler, and as a result the...

    How can I upgrade my powermac g5???

    I had recently gotten an old PowerMac g5 from a local school of mine and loved it as I used to have one when they first came out. It needed a hard drive and a good cleaning, so I installed a 500GB Samsung 850 Evo I had laying around, and got a 10.4 tiger disk from an old local mac store and...

    Hi All, I'm new here, and a first time Mac use, so I hope this goes to the right place?

    G5 Quad boots but #7 RED LED turns on and then off briefly, then goes to sleep.

    So I have a G5 quad and it boots ok, then the fans start to get pretty loud (I don’t believe full speed but I would say faster than it should be, but then after a couple of minutes, it freezes up and goes to sleep (sometimes it just freezes on what ever screen your on). I checked the LCS and it...

    PowerMac G5 Linux Performance

    I haven't seen a G5 be so fast on the internet before, is this video real? YouTube plays smoothly at 720p 60 frames per second using firefox 47. Is 16.04 ubuntu always this good on older G5's?
