The switch itself
On iPhone or iPad, open Settings → General → Software Update → Beta Updates and select the public beta option for the release you are on. On a Mac, the same control lives in System Settings → General → Software Update behind the ⓘ next to Beta Updates.
That's the whole procedure. No restore, no erase, no data loss — you are simply changing which channel offers you future updates.
What happens to your current build
Nothing immediately. Your device keeps the developer build it already has. Because the developer channel runs roughly a week ahead, you will typically receive no updates at all for a while — until the public channel catches up to and passes your current build.
This period of apparent silence is normal and often mistaken for a broken switch. Your device is simply ahead of the channel it just joined.
Why people switch
The usual reason is stability. The public channel skips the roughest builds and applies a week of extra bug reports, which matters most on a device you depend on daily.
The other common reason is exit planning: the public channel converges with the Release Candidate at the end of the cycle, making the eventual switch to stable software seamless. Our channel comparison covers the trade-offs in full.
Switching the other way
Going from public to developer works identically and takes effect much faster, since the developer channel is ahead — you will usually be offered a newer build within minutes.
Both switches are reversible at any time, and neither affects your data.
Why the switch sometimes does nothing
Changing the channel does not change the software already installed. It changes which builds you are offered next — and because the public channel is two to three weeks behind, its current build is often older than the developer build you are running. iOS will not offer you an older version, so nothing appears to happen.
What actually resolves it is time. You stay where you are until the public channel catches up and overtakes your build, which usually takes one or two cycles. There is no way to accelerate that short of a full restore to an older signed version, which erases the device.
This is worth knowing before you switch rather than after, because the same rule applies to turning betas off entirely: the setting takes effect for future updates, not retroactively. Our exit guide covers both the wait-it-out route and the restore route.
Frequently Asked Questions
Do I need to restore to switch from developer to public beta?
No. Just change the channel in Settings → General → Software Update → Beta Updates. Your data and current build are untouched.
Why am I not getting updates after switching to public beta?
Because your device is already ahead of the public channel. You'll start receiving updates once the public channel passes the developer build you're currently on — usually within a week or two.
Is the public beta the same software as the developer beta?
Essentially yes, released about a week later. The public channel skips builds that proved unusually unstable, and both channels converge at the Release Candidate.
Can I switch back to the developer beta?
Yes, at any time and just as easily. The developer channel runs ahead, so you'll typically be offered a newer build almost immediately.
