I have a late 2008 MacBook Pro running Catalina that I still use daily. As far as I can tell it still receives security updates.

There's a simple patcher you can use for these old macbooks:

Neat, does that include System Integrity Protection and Authenticated Root Volume on your hardware?

from what i remember open core doesn't need to disable sip to function, just to install. the firmware is the actual firmware upgrades released by apple [everyone was shocked they supported this] that come embedded in the osx updates. my updates worked fine.

I'm pretty sure sip gets re-enabled each boot, but to check for authenticated root volume i think i need to install the g20 to run crutil or whatever it is.

happy to hear that I'm not the only one [sys admin type person] doing this.

although i use Windows, i do have Catalina installed [and Debian for the triple boot]. also using open core. I'm pretty sure i downloaded a copy of osx from one of their repositories 0.o I'm super lazy, it's really not that hard.

my average cost for hardware since i bought my Mac is now less than 400/year CDN. is it worth it? while I'm slightly concerned about the security [I'm probably the biggest risk anyways since I'm not confident in my knowledge of secops], i get 95 fps playing pubg, can edit in 4k, run 100+ tracks in Cubase, and run 3 different OSes or as many vms as you'd like [which i think can also run bare metal vm on the 144 firmware upgrade]. on top of that the case still looks good and I've kept at least 50+lbs of ewaste out of landfills or whatever... seems pretty worth it [hopefully no one ever tries to steal pictures of my cats]

[we could also get into a discussion about the right to repair bill in the EU, talking this way]

do you game? i feel like that might have been intentionally left out of the interview?

what info would you keep unencrypted on your servers?

how much does a colo cost for a 2u server typically? how about back in 06?

is rsync a good solution for video files backup? what are the benefits over say, running a home server and keeping physical backups at your friends house or iron mountain or something?

can rsync use 'live' encrypted data? in other words, how do you encrypt/decrypt on the fly? say for streaming an mp3 or something? [not that you would do this if you were paying per GB...]

please excuse my ignorance. I'm not a real sys admin, just an old wanna be hacker that could never get his shit together.
