A bigger RAM number on the spec sheet doesn't automatically mean you'll never see memory pressure. Here's the honest picture for M5 Macs specifically.
What the M5 lineup actually offers
The M5 MacBook Air, announced March 3 2026 and available from March 11, starts at 16GB of unified memory, a genuine upgrade over the M4 Air's old 8GB base. 24GB and 32GB configurations are available as paid upgrades. The M5 Pro and M5 Max MacBook Pro models go considerably further, supporting up to 128GB of unified memory on the highest configuration, aimed at professional video and machine-learning workloads.
Real buyers are still seeing memory pressure
Despite the improved baseline, forum threads on MacRumors and Apple Community already show M5 Pro owners asking variations of "is this normal memory pressure for a Pro chip?!", describing yellow or red memory pressure indicators on 24GB configurations with only a browser and a few everyday apps open. This mirrors what happened with 8GB M1 and M2 Macs: more RAM helps, but it doesn't eliminate memory pressure if your workload or number of open apps and browser tabs scales up to match it.
This is consistent with how unified memory works on Apple Silicon: the CPU, GPU, and neural engine all draw from the same shared pool, so a demanding graphics task or several browser windows with dozens of tabs can put real pressure on a 24GB machine the same way heavy multitasking pressured 8GB machines a few years ago. The absolute numbers moved up; the underlying dynamic didn't change.
How much do you actually need?
16GB (M5 Air base): Comfortable for browsing, email, writing, light photo editing, and most everyday non-professional use. This is a real improvement over the old 8GB base and should feel noticeably more headroom for typical daily use.
24GB: A sensible middle ground if you regularly run several apps simultaneously, keep dozens of browser tabs open, or do moderate photo/video work. Based on the early complaint threads, this tier can still show memory pressure under genuinely heavy multitasking, so it isn't a guarantee of zero pressure, just less frequent pressure than 16GB.
32GB and above (Pro/Max): Aimed at video editing, 3D work, local AI model work, or running multiple virtual machines. If your work genuinely uses this, the extra memory earns its price. If you're buying it "just in case" without a specific heavy workload, you may be paying for headroom you won't use.
What to do if you're already seeing pressure on an M5 Mac
Check Activity Monitor's Memory tab first: sort by memory use and see what's actually consuming it. Browser tabs and their helper processes are the most common culprit on any Mac, regardless of chip generation; see how to reduce Chrome's memory usage on Mac if that's your main browser. Login items that launch automatically also add up over time; this guide covers auditing them.
If pressure builds up gradually over a working session rather than being immediately caused by one obvious app, a quick way to reclaim headroom without restarting is asking macOS to release memory it's holding for apps you're not actively using. Shiny does exactly that from the menu bar in one click, for $4.99 once, which is a considerably smaller outlay than jumping to the next RAM tier if the underlying issue is background clutter rather than genuine workload demand.
Is upgrading from an M4 or M3 Mac to M5 worth it for memory alone?
If your current Mac is an 8GB M1 or M2 model and you're regularly hitting memory pressure, the M5 Air's 16GB base is a genuine, meaningful upgrade. If you're already on a 16GB M3 or M4 Mac and it's serving you fine, the M5's memory ceiling isn't itself a reason to upgrade; the chip's other improvements (efficiency, Wi-Fi 7, battery life) would need to be the deciding factor instead. For the general buying-decision framework, should you buy more RAM or a new Mac covers this trade-off in more depth, and 8GB vs 16GB Mac covers the same question for the outgoing generation.
Why the RAM shortage makes this decision harder right now
2026 has seen an industry-wide DRAM shortage that's pushed up the cost of memory across the board, including Apple's own RAM upgrade pricing, and contributed to MacBook Pro shipping delays of up to two months on some configurations. That means jumping a RAM tier costs more right now than it typically would, and getting your hands on a higher-configuration model may simply take longer. Both of these are good reasons to be more certain your workload genuinely needs the upgrade before paying for it, rather than treating a bigger RAM number as free insurance against a problem that might actually be background clutter rather than real capacity need.
A practical test before you spend anything
Before deciding you need a higher RAM tier, or before paying the current elevated prices for one, it's worth ruling out the cheaper explanation first. Open Activity Monitor during a normal working session and watch the Memory tab for a day. If the pressure spikes correlate with specific heavy tasks (large video exports, dozens of tabs, a demanding creative app), that's a genuine workload signal pointing toward more RAM. If the pressure builds up slowly over hours regardless of what you're actively doing, that's much more likely to be background apps and forgotten browser tabs accumulating, which a $4.99 tool solves for a fraction of the cost of the next RAM tier, current shortage pricing included.
