How Long Should You Keep a Mac Before Selling?

There's no single right answer to how long you should keep a Mac before selling it — but there is a right way to think about it. Two clocks are running from the day you buy: how long the machine stays genuinely useful, and how long it holds enough resale value to be worth selling. The sweet spot is the window where those two clocks overlap, and most owners either sell too early and lose years of use, or hold too long and watch the value quietly bleed out.

Here's how to find your own overlap.

The two clocks that decide it

The usefulness clock runs long. Macs typically deliver five to eight years of reliable service, and Macworld notes most users get "five to eight years of reliable performance" out of one before it starts feeling its age. The value clock runs shorter: resale prices are highest early and settle into a long, gentle decline before fading in the final years. Sell before the usefulness clock runs out but after the steepest value drop, and you've timed it well.

The macOS support window is the real deadline

The hard limit on a Mac's life isn't the hardware — it's software. Apple keeps the three most recent versions of macOS patched, which works out to roughly eight years of security updates from a model's launch, per Macworld. After that, a machine still turns on but stops getting the fixes that keep it safe to use online, and its desirability on the used market falls with it.

Intel Macs are the cautionary tale playing out right now. macOS Tahoe is the last release that will run on Intel-based Macs, and Computerworld reports Apple will keep pushing security updates for a couple more years, meaning those machines "cease to be secure in 2028." Owners who wait until that deadline to sell will find the market has already moved on.

There's a parts clock too. Under Apple's service policy, a Mac becomes "vintage" five years after it was last sold and "obsolete" after seven, at which point Apple stops offering hardware service. A machine sold while it's still fully supported is far easier to move than one already wearing the vintage label.

The residual-value clock

Value doesn't fall evenly, which is what makes timing matter. The first year is the steepest, then depreciation slows to a crawl through the middle of a Mac's life before picking up again toward the end. That long flat stretch — roughly years two through four — is where you can hold onto the machine at almost no cost to its resale price, getting more use out of it while giving up very little value.

What you want to avoid is drifting past that plateau into the years where value declines steadily and a battery or repair issue can knock a real chunk off any offer. Selling while the machine is still modern, functional, and fully supported is consistently what commands the strongest price.

Signals it's time to sell

Regardless of exact age, a few triggers mean the window is closing:

• Support is ending soon. If your model is one or two macOS versions from being dropped, sell before that happens, not after.
• A refresh is imminent. Resale prices on the outgoing generation typically slip 15–20% in the weeks after Apple announces a new model, so selling ahead of a rumored update protects your price.
• The battery is fading. Battery health is one of the first things buyers and buyback services check; sell before capacity drops far enough to require a replacement.
• You've outgrown the specs. If limited memory or storage is making the machine feel slow, a buyer with lighter needs will still pay well for it today — that won't be true in two more years.
• It's approaching vintage. Once a model nears the five-year mark since it was last sold, its value and serviceability both start to slide.

Hold or sell: matching the timing to how you use it

If you upgrade on a regular cycle and care about resale, the two-to-four-year plateau is your window — you capture most of the machine's residual value and hand the next owner a Mac that's still current. If you'd rather run a Mac into the ground, that's a perfectly good plan too; just don't let it coast past the support cliff, because a Mac that no longer gets updates is worth far less and harder to sell. The costliest mistake is the accidental one: keeping a machine "until you get around to it" and discovering it went vintage while sitting in a drawer.

Whichever camp you're in, the move is the same when the signals line up — check the number before you commit. An instant offer takes about thirty seconds, and it's the fastest way to see whether you're still on the plateau or already sliding down the far side.

The bottom line

How long should you keep a Mac before selling? Long enough to get real use out of it, but not so long that you sell into a dead market. For most people that means somewhere between the two-year plateau and the five-year support horizon — sell while it's still supported, still desirable, and still holding value, and you get the best of both clocks instead of losing to one of them.
