Macbook Pro M2 Pro or M2 Max

if you have an M1 MacBook Pro now, you should find out why is stutters under load before you buy ANYTHING.

key to this could be Activity Monitor. I suggest you open Activity monitor.

from its view menu, select 'all processes'

Choose The Memory pane and watch to see if you are using any 'Swap' when you open all this stuff at once. If the memory pressure graph shows anything but all green throughout the process, you need more memory to support that activity.

There are additional ways to evaluate CPU usage and other things as well.

¿How much RAM in the machine that is getting slow?

If you are planning on keeping this new MacBook Pro for a bit, I would suggest that you go with the M2 Max chip and pay the extra $'s for the 32gbs at the minimum; in the long run, you will be happier with 64gbs or even the 96gbs of memory.

Go for at least the 2 TB SSD Storage and at least consider the 4 TB SSD. Yes, it will be an expensive machine, but it should last for several years, and by all means, invest in the Apple Care + plan for this machine.

I would recommend getting at least 16 GB of RAM. Some people say you can get by with 8 GB, but Adobe recommends at least 16 GB for each of their major programs (Photoshop, Lightroom, Lightroom Classic).

It sounds like you have the 13" M1 MacBook Pro, which is more like the 13" M1 MacBook Air than its 14"/16" namesakes. The MacBook Airs and 13" MacBook Pros

• Use the 'base' M1 and M2 chips
• Have two USB4 (Thunderbolt 3) ports
• Have a limit of one external display
• 8 or 16 GB of RAM (M1)
• 8, 16, or 24 GB of RAM (M2)

When you jump up to the 14" and 16" MacBook Pros, you get

• 'Pro' or 'Max' chips
• Three USB4 (Thunderbolt 4) ports, a HDMI port, and a SDXC card reader
• More or faster CPU cores (which might matter for long batch jobs more than for interactive work)
• Stronger GPUs
• The ability to drive at least two external displays
• 16 or 32 GB of RAM (M1 Pro, M2 Pro)
• 32 or 64 GB of RAM (M1 Max)
• 32, 64, or 96 GB of RAM (M2 Max)

RE: "if you have an M1 MacBook Pro now, you should find out why is stutters under load before you buy ANYTHING."

Second this recommendation, and the advice to check Activity Monitor while running a typical workload.
