It has said five minutes remaining for the last hour. There is no error, no warning and no button to press, just a bar that has stopped caring.
That is a different situation from an install that has failed. It wants a different response. A failed install tells you something. A stuck one tells you nothing at all, which is why people panic and pull the plug.
I went through Apple's own troubleshooting page line by line looking for the word stuck. It is not there, and neither is any statement about how long an install should take.
Stuck and failed are not the same problem
The split first, because half the advice online answers the wrong one.
⛔ A failed install shows you a message. Something about downloading, preparing, verifying or personalising, and that is its own list of causes.
⚡ A stuck install shows you nothing. The bar is still there, and so is the estimate. Neither has moved.
⭐ This page is about the second one. If you have an actual error on screen, go and read the other one instead. The causes barely overlap.
What that time estimate really is
The single most useful thing to understand here.
⚠️ Ours, and marked as ours: the minutes remaining figure is a guess made from how fast the first part went. It is not a countdown, and it is not a promise.
⛔ An installer that hits a slow stage after a fast one keeps showing the old estimate. So the number sits still on your screen while real work carries on underneath it.
⚡ The bar itself can be worse than the number. Long stretches of a macOS install do not move it at all, because nothing being done maps onto a percentage.
⭐ So a frozen estimate is normal. A frozen bar is normal too. Neither of them, on its own, means anything is wrong with your Mac.
How long is genuinely too long
The real answer, with the part nobody wants to hear.
⛔ We could not find any statement from Apple about how long an install should take. Its troubleshooting page covers errors and never mentions duration. So there is no official figure at all.
⚠️ Ours: give it several hours before you decide, not several minutes. An older Mac, a large update and a slow connection all stack up. The last stage is the slowest.
⚡ Apple documents that the installer is doing more than copying files. Its installation troubleshooting page says the installer needs a connection "to download macOS and get firmware and other information specific to your Mac model".
⭐ Firmware is the reason for the patience. That is the part of the process where interrupting it does lasting harm.
How to tell it is still working
Three checks, none of which touch anything.
⚡ Look for heat and fan noise. A Mac that is warm or audible is working, whatever the screen says.
⭐ Note the exact bar position, then leave it half an hour. A hair of movement is enough. That proves it is alive.
⚠️ Try the Caps Lock light if your keyboard has one. A light that toggles means the machine is still responding, not hung.
⛔ And if the screen has gone black with the fan still running, that is often normal too. Displays sleep during long stages.
The one thing not to do
Said plainly, because it is the mistake that turns a wait into a repair bill.
⛔ Do not hold the power button during the first few hours. Apple's own page notes that a persistent problem can end with needing to "revive or restore Mac firmware".
⚠️ That is the state you can create yourself by cutting the power at the wrong moment.
⚠️ Do not disconnect a laptop from its charger either. An install that runs out of battery halfway through lands you in the same place.
⭐ Ours: if you have to leave it, leave it plugged in and leave it alone. Overnight is fine, and a perfectly reasonable thing to do here.
If it truly has not moved, in this order
Only once you have genuinely waited.
⭐ Force a restart with the power button held down, then let it boot normally. Most come back and finish on their own.
⚡ If it will not boot, go to macOS Recovery. Apple's advice is to "Install macOS from macOS Recovery", so that nothing else on the Mac can interfere.
⚠️ Documented by Apple, before you reinstall: "Use Disk Utility to repair your startup disk from macOS Recovery."
⛔ Apple also says that if you are installing through the App Store or Software Update rather than Recovery, "it might help to start up in safe mode before installing".
⚡ And check storage while you are there. Apple's first item is that if the message says your Mac does not have enough space, you free some up.
⛔ And if you are building a USB installer rather than updating in place, the not a valid installer error has its own causes.
The gap in Apple's page, named
Because the reason you found nothing needs saying out loud.
⛔ We could not find the words stuck, frozen or hung anywhere on Apple's installation troubleshooting page. Every item on it assumes an error message you can read.
⚠️ That is exactly why this search goes unanswered. People with no error have nothing to match against. They end up guessing at advice written for a different fault.
⭐ Ours: treat the absence as information. If Apple lists no cause for a silent stall, the commonest explanation really is that it is still working.
Ours: the limit on this page
Stated up front rather than buried.
⛔ There is no Mac in this room. Nothing below was reproduced on hardware. Every documented step is Apple's own wording, read from its page and quoted, and every judgement is marked as ours.
⚠️ What that means for you in practice: the quotes are solid, and the timing advice is reasoning rather than a stopwatch reading.
Status: read against Apple's macOS installation troubleshooting page, 26 August 2026. Apple supplies every quoted step. ⛔ It names no stuck install and no duration, and no Mac was available here.
How long should a macOS update take?
Apple does not publish a figure. We could not find one on its troubleshooting page either. Plan for hours rather than minutes on an older Mac or a slow connection, and treat overnight as normal rather than alarming. The last stage is the slowest and the least visible, so the end always feels longer than the middle.
Is it safe to force restart during a macOS update?
Not in the first few hours, no. Apple's own page ends with reviving or restoring firmware for persistent installation problems, and cutting power partway through a firmware write is one way to get there. Wait, look for heat and fan noise, and keep your laptop on its charger while you do.
My progress bar has not moved for an hour. Is it frozen?
Probably not. Long parts of a macOS install do not move the bar at all, because the work being done does not map onto a percentage. Note where the bar sits. Walk away for half an hour and look again. Any movement at all means you should keep waiting.
What if my Mac restarts and still will not finish?
Then start it in macOS Recovery and install from there, which is what Apple recommends so that no other software can interfere. Repair your startup disk with Disk Utility first while you are in Recovery, and check you have free space, because that is the first thing on Apple's list.
The Short Version
- A stuck install and a failed install are different. This page is the silent one.
- The minutes remaining figure is a guess from early speed, not a countdown.
- Long stretches of a macOS install move neither the bar nor the estimate.
- Apple publishes no expected duration, so give it hours, not minutes.
- Heat, fan noise or a working Caps Lock light all mean your Mac is alive.
- Do not hold the power button early, and do not unplug your charger.
- If you must intervene, force a restart, then install from macOS Recovery.
- Repair the disk with Disk Utility in Recovery before you reinstall.
Where to Next
Note exactly where your progress bar sits, then leave the Mac alone for half an hour without touching it. That single check answers the question you came here with.
Keep it plugged in while you wait. A laptop that runs flat mid-install turns a delay into a real problem.
If it is still identical after several hours, force a restart and let it boot. Most finish by themselves once they come back.
If you have an error message rather than silence, you are on the wrong page and I would rather send you to the right one. The failed install has its own causes.
If yours eventually finished after an unreasonable wait, say how long it took in the comments. Real numbers from real Macs would help the next person more than anything I can measure.
