I understand why you're getting downvoted but I also am in some form of agreement with the sentiment/hope they don't lose sight that they are pretty much keeping the dream of the consumer UNIX vendor alive.

You don't matter to them. The "What's a computer?" ad shows what they care about. Do what they want and stay on the happy path. Otherwise, you're holding it wrong.

Desktop linux has some market share in hollywood, I would think that market does matter to them as it did SGI etc.

How did you end up with TM backup larger than original source? Sure, total storage consumed on TM drive can be larger than source, but that is because older versions of files are stored as well. But restoring most recent versions of files should be equal to source in size.

I had only 600-700 gb of data on my Mac. Installed OneDrive, did not know that I had configured my NAS to do 800gb of cloud backups to OneDrive. And Time Machine downloaded that data into its backup. Although I had configured OneDrive not to download that folder to my Mac. So time Machine screwed up in the first place.

Ah, ok, that's a nasty bug/scenario. I long for the good old days one could just rsync the internal drive and bless it and you have a bootable clone, or make compressed disk image. Those were the days.

Keyboard Maestro is a lot more powerful than what you're thinking of. A sequence of shell commands bound to hotkeys is in no way an adequate replacement.

Do you have any examples of use cases Keyboard Maestro is great for?

When building macros you can leverage OCR and image recognition so it can know how to find elements on the screen that you need it to click. I have barely scratched the surface of what it can do I am sure there is lots more.

This is from the SuperDuper backup folks. SuperDuper is a tool that you can use to make bootable backups of your macOS system. Apple took away the ability for 3rd party tools to manipulate the OS and copy it to another partition/drive and took it upon themselves to provide that functionality via a utility. That utility is apparently non-functional in 15.2. So that breaks SuperDuper's ability to make a nice, clean, bo…

I wonder if Carbon Copy Cloner is affected. Having bootable backups was the only reason I ever moved to a Mac. This means, a backup of my computer created using something like Carbon Copy Cloner, or SuperDuper backup when plugged into any other Mac, and it would boot as my computer. Also known as Target Disk Mode booting off this backup. Indispensible when or if my laptop was in for repair with Apple.

TimeMachine is a pretty good second option. It's not bootable itself, but the recovery console on any mac can ingest a time machine backup and get you back up and running quite quickly. The benefit here is that it's free, trivial to setup, and very easy to keep running; Given an empty disk, plug it in, click one button, done.

Yup both Mac and Windows have a better replacement now: Linux. Thanks to all the hardware vendors and Valve, Linux has become a better desktop alternative for sure.

The day Microsoft decides Proton is a nuisance that gaming alternative is gone, as Valve decided fostering a GNU/Linux game ecosystem wasn't worth it.

I'm not quite sure what you are saying here but Valve can beat Microsoft at almost any game.

64GB of system RAM and partial offload to a laptop 3090 or 4090 will run 32b unquantized.

Will I get an answer back anytime soon? On a MBP pro it's conversational speed.

Nope, on cloud it is faster than conversational where you can skim to the right place or quickly regenerate seeing it is going down the wrong path.

Time Machine is OK as secondary, never primary, or the sole option.

Having Target Disc Mode and Target Display Mode on a Mac are two of probably the 4 reasons I switched to a Mac from Windows. Skitch was the other, and CC/SuperDuper was the 4th. I had tolerated my last windows laptop dying :)

Multiple copies of multiple types of backups is the only way.

I have always maintained a CarbonCopy/SuperDuper at all times, plus a Time Machine that I cared far less about. Time Machine is my desperate fall back.

Time Machine backups haven't always been super reliable, nor is the recovery time to restore acceptable. I'm sure it's gotten better, but enough for me to forget what it hasn't done in the past? Doubt it.

Time Machine is kind OK for set it and forget it backup to a NAS or something. I didn't find as much value in Time Machine to a dedicated external drive since it had the risk of being the only backup, and it's not a backup if there's only one copy. Time machine's limited utility of use when there is an emergency on an external drive, compared to SuperDuper/Carbon Copy Cloner which is you are up in minutes not hours or days while you figure out what is going..

Having a Carbon Copy/Super Duper external drive sitting at one of your desks that's regularly plugged in gives you a live replica should anything happen.

Time Machine has it's own history of issues:

This is bad. - Just recently I broke my system badly. So I decided to erase my system and re-setup from time machine. After several unsuccessful attemts I realized that my Time Machine backup (1.45 tb) exceeded my ssd capacity (1 tb). I did research, and learned not to prune my Time Machine backups. As that may corrupt it. So after several days and failed attempts to restore from time machine and after some research…

"Create a fresh install and manually (!) copy individual files from time machine to your mac.“"

This is, and always has been, the only sane answer.

If you value your time, energy and sanity you do not upgrade your OS - you wipe it clean and install from scratch. It is as true today with OSX as it was going from Windows 3.1 to Windows 95.

I take that to mean that it is basically so slow as to be useless and that you would in fact need a Macbook to be able to run this model locally.

This whole thread has become a bit frustrating with comments about how other laptops are competitive with a Macbook. But no one can actually name a single laptop that can do all the things that a Macbook can.

Apple is sitting on a massive pile of cash but won't dedicate a team to develop their own Unix userland tools. That's how much they care about the underpinnings of MacOS and power users.
