I don't always work on making brochures, sales sheets, logos, websites, etc. That represents about 30% of the work I do. The rest is pretty much intensive office work.
I have graphic intensive proposals that have 60-80 pages in InDesign at times. Not all the time, but sometime.
Here's another thing I am wondering about. Would the 2X faster SSD (as Apple claims) make a difference? Would it negate the need for more RAM?
According to that, 15 GB of your used memory is cache which is of minor importance on a machine with fast SSD. Of the remainder, only 5 GB is
active memory in RAM, and you haven't even hit memory compression yet.
the TLDR is this:
because your machine has an excessive (or lets say "plentiful") amount of memory, macOS is doing its best to try and make use of it for SOMETHING (cache) rather than having it sit idle (because idle memory is wasted memory), and you're still using less than half the total system memory - my suspicion is because you haven't worked with more than 15 GB of data since the machine booted, or macOS is internally deciding that 15 GB of cache is more than enough and beyond the point of diminishing returns.
Basically macOS has put everything you've touched into memory and has run out of things to put into cache because it doesn't know what to put in there yet. It has literally run out of things to try and keep in memory for you "just in case" - even if they aren't active.
My view is that exact workload would fit in a 16 GB machine with minimal performance impact.
You might barely start to hit memory compression, but the machine would cope well with it IMHO (and in the case of having a faster SSD and faster CPU/etc. in the m1 you'd probably see a performance uplift that would more than off-set that, is my bet).
You could probably even
run that workload in 8 GB, but the machine would certainly struggle and you'd see a big improvement with 16 GB. 32 GB you'd maybe see a minor improvement due to having plenty of disk cache. 64 GB for that workload is beyond the point of diminishing returns imho. I'm not saying you made a mistake going for 64 - because
RAM is cheap (and it's definitely better to have more than not enough). And you're somewhat future proof.
But unless you start doing significantly different things with that machine that need much more RAM, you'll likely be hitting the wall with CPU and GPU before 32 GB becomes a limiting factor.
From your list, it's not uncommon for me to have all of these:
- Mail
- Spark
- Safari (many more than 2 tabs
)
- Calendar
- Contacts
- Reminders
- Messages
- Maps
- Music
- Podcasts
- Books
PLUS a 4 GB virtual machine running in Fusion, plus Skype for Business, Excel, Word, a bunch of safari tabs, Brave, Firefox (where I work I use 3 browsers for different things

, Cathode/Terminal, MS Remote Desktop, News, Bbedit and/or visual code running at the same time.
