I guess you've never worked with RACF, the security framework for MVS
(or as it's now known, "Z/OS").
It's an ADD-ON.
Yes, you read that right. If you don't run RACF you don't get
security at all. When RACF is running, it installs hooks into the
OS so that when you attempt to open a dataset (that's what a file is
called on a mainframe) it first runs a RACF hook to see if you're
allowed to do that.
(Then if you're running DFHSM it might restore the dataset from a
backup, in case it was migrated off to tape ... just because it's in
the catalog doesn't mean it's actually there)
Mainframes are weird. But I paid my way through college working
summers in a mainframe shop so it's all good.
I wish I could have had the chance to use a mainframe computer or miniframe computer. I would have liked to played with OS400.
I don't know if this was my original quote - but since then, I've had great luck with getting NTFS external drives to mount automatically under Debian Gnome.
But, at least on OS X Classic - I know that NTFS isn't a natively supported filesystem... there is an aftermarket NTFS app you have to buy.
OS X Intel I've never had a problem - and even my Amiga can easily access SMB file shares. :)
Mon May 02 2022 09:51:11 MST from OppieI think OS X will have the advantage here, as I can plug in Windows
formatted external drives and I think they'll mount automatically -
which I doubt is the case under Linux.
Linux does automount a NTFS windows formatted drive.
Catalina just fell out of support at the end of October though, so I'm debating what is next with the thing. It has Broadcom Wifi, which is PITA under Linux or any BSD, but I do have a little USB Wifi dongle that is well supported and 802.11n. Was thinking it would make a delicious OpenBSD machine, but it'd probably run Debian just as well. It sits next to a 2018 MBP running Ventura so I don't really need macOS on it. Any suggestions? I'm not a GNOME or KDE guy, can live with Xfce but I'd be just as happy with Afterstep or something.
I honestly don't see the value in running non Apple OS on Apple hardware. You can always find something less expensive, of equivalent speed, quality and power, with a PC. The thing that makes Macs worthwhile is that OS X is actually a pretty nice OS.
I can never keep track of OS X names though. I've got Sierra on mine. Tried to move it to High Sierra, and it caused problems, and falling back to Sierra was sketchy. This is what I hate about Macs. A failed OS install may make firmware updates that can prevent falling back. It is an OS and Hardware combo that can literally brick itself. When I got my current machine, it was pretty bricked - and it took some effort and a little bit of non-Apple Authorized tinkering (it was basically a Hackintosh at one point in the recovery process) to get it back up and running.
What model? The 2012 MBP with discrete AMD graphics are notorious for cooking themselves. Actually, most of the Macs of that era have heat dissipation issues that can cook them. Running a non Apple OS can exasperate this issue - as a lot of alternative OS platforms don't have the fan logic that is built into OS X.
Mine is a 2012 MPB i7 15". It is probably the most notorious for these issues.
But, I mean, if you've got one lying around and you don't need OS X... I'm pretty partial to Debian... I played around with Ubuntu for a while - but Debian worked best for me with Citadel - and though people claim it isn't suited to a desktop OS machine - I think it works fine in that capacity.
Thu Nov 10 2022 17:34:03 MST from greg nesbittSo, I acquired a nice 2012 MBP recently. Someone had already refurbed it a little, put 8GB RAM in it 1TB spinning rust. The newest OS it will run is Catalina. With the 1TB disk it is slow as molasses. I swapped it with a 512GB SSD and that made a huge difference.

Just checked. This one is an A1286, Mid-2012 15" MBP with the AMD discrete graphics. Not sure if it's the 2.3GHz or 2.6. In any case I think I'll just stick with Catalina on it for now. I dropped homebrew on it yesterday. They aren't supporting Catalina anymore but all of the packages I tried still worked just fine.
Ok. That is ground zero for the problem. It is what I have. Few of them survive. There is a utility to show you if it is running on discreet GPU or built in video. Do not allow it to run on the discreet GPU. This means don't run programs that switch it to the GPU, because you can't disable it by software or hardware switch, and even hacking blobs doesn't work. There is a company that will actually cut the GPU traces and wire around it - but that is expensive for an i7 so old modern i3s run faster than it.
Install SMCFanControl, TG Pro and gfxCardStatus.
It is also a good idea to disassemble, remove the heatsync, and reapply heatsync to the CPU.
I have the same model, had to read all up on it. Considered the service, but shipping the mb away to get the GPU cut and have it returned - at the cost required, didn't make sense.
