How do security patches work in MacOS 10.9 and 10.13 dual boot
I use OS X 10.9 for my professional work. since the security flaws were found in recent Intel chipsets, I have kept my system offline (as to patch it would negatively affect performance, i read).
Now i’d like to create a second boot/partition (running OS X 10.13), to go online. if I apply the security patch to this second partition, will it (negativity) affect my offline boot? (running OS X 10.9)
How do these security patches work? are they patching the system/OS, or do they patch the bios/CPU?
Apologies if im getting some technical terms wrong… this is not my field of expertise!
thanks for your time/help,
thanks so much for that detailed reply!
i think i should add some more info;
regarding the older OS X boot (10.9), i really am adamant about keeping it as it is (but offline). I use it for audio production, and i know how it runs on on 10.9 (smoothly). it’s been really steady & i’m 80% through the production of an album. i’m sure i will update it to 10.10/10.11 (maybe newer?) at some point, but for now i am happy with it as it is (and so long as it’s offline, it should be safe… i think). it’s also an older Mac (quadcore 2012 Mini), and in my experience, older Macs seem to run better (performance-wise) on older OS versions, ones that aren’t too much newer than the machine themselves - and i regularly push the little Mini to its limits, so i need it to keep performing well.
regarding the admins & antivirus; yes, good points! i do run my systems with several logins, with a separate admin - but thanks for the reminder! and the same is true for anti-virus. and also a good tip re internet banking.
regarding the diff file structures between newer versions of OS X and 10.9; also a good reminder, thanks. i would have 10.9 and 10.13 on completely separate SSDs, so i don’t think this will be a problem. and in terms of file access, i would want to go the other way (accessing older files from newer OS). i was also thinking i would use a USB to move the files between the systems (to upload/download audio online, between the two).
i should also add that all of this is meant to be a temporary solution. my 2011 Macbook Pro has succumbed to the dreaded graphics card problem and i need some more time to sort it out. but in the meantime, i have some work (research, emails, some basic website construction) that i need to do. ultimately i’m trying to buy myself some time, so that i can approach the dead Macbook Pro with a more level head! (it’s been driving me mad - i will probably return to these shores looking for advice).
so in the meantime, i’ve been toying with the idea of booting my 2012 Mac Mini (that is normally frozen offline at OS 10.9), from an external SSD (OS 10.13) to get back online. i did a speed/feel test yesterday, and it’s nice and fast (via an external firewire enclosure).
regarding the question of the security patches, you’ve given me more to research and i think you’ve answered my question - thank you, again.
i think i will go ahead and clone/back up my system (in case it goes wrong) & then try 10.13 on the external drive. but i’ll do a little more research first, based on what you’ve said.
thanks so much!:)
Is this a good question?
