Nearly running out of memory space and looking for effective ways to upgrade Mac RAM?

Should I Upgrade RAM?

RAM is the abbreviation of Random-access Memory. For daily use, the 8GB memory space is enough. There is no need to upgrade RAM unless you have to run multi-task or intensive activities at the same time.

If you are running out of memory space, you can free up RAM rather than upgrade it.

The RAM is mostly soldered in the motherboard in the recent Mac models, making it impossible to upgrade.

To check the RAM usage on Mac:

  1. Open Activity Monitor via Spotlight.
  2. Klick the Memory tab.

The Memory Pressure is what you need to focus on. The green means the memory condition is well. Also from this, you can view how much memory space you have already used.

In the case that it shows yellow or red, it reminds you that the memory condition is not that well. And you may need to upgrade or free up RAM.

Can You Upgrade RAM on Mac?

Not all Macs can upgrade RAM. To make sure whether you can upgrade RAM on your Mac, check your Mac model and memory slot.

  • To check your Mac's memory slot: Go to Apple MenuAbout This MacMore InfoSystem Report>click Memory under Hardware.
Check Memory Slot Mac

If there is no memory slot information, it means your Mac doesn't have a memory slot. The RAM may be soldered into the logic board. If there are memory slots, check what shows next to the Upgradeable Memory. No means you can't upgrade your Mac RAM.

  • To check your Mac models: Go to Apple MenuAbout This Mac.

After checking your Mac models, go to the next section and find the corresponding RAM upgrade method.

It's worth noting that only a few models have slots for additional RAM. If you are using an older Mac without a memory slot, the best way to upgrade RAM is to buy a new Mac/MacBook.
