Tap "Join Beta" on CodeWing: Return to this page and tap the Join Beta button above. Safari will trigger the official TestFlight invitation link. If prompted with "Open in TestFlight?", tap Open.

Essential Beta Testing Tips:
Apple 10,000 Tester Cap: Apple limits public TestFlight groups to 10,000 active users. If slots are currently full, tap Get Slot Alerts above to be notified the second a slot opens.
100% Free Sandbox Purchases: In-app purchases, subscriptions, and pro features in TestFlight are simulated in Apple's sandbox environment at $0.00 — your Apple Account is never billed.
90-Day Build Lifespan: Each build expires after 90 days. Developers periodically push updates that reset the countdown, and your personal app data is preserved.
Revert to App Store Anytime: You can switch back to the public release at any time by redownloading UTM Virtual Machines directly from the regular App Store.

How do I join the UTM Virtual Machines TestFlight beta on iOS?
First, download Apple's official TestFlight app from the App Store on your iPhone. Then return to this page and tap the "Join Beta" button above. Your device will automatically open TestFlight and prompt you to accept the developer's beta invitation. Tap "Accept" and then "Install" to start testing UTM Virtual Machines. If it says "This beta is full", tap "Get Slot Alerts" to be notified instantly when a slot opens.
Is testing UTM Virtual Machines on TestFlight safe and free?
Yes, testing UTM Virtual Machines is 100% safe and free. Every public TestFlight build must strictly follow Apple's App Review Guidelines and passes Apple's automated and manual security checks before public invitation links can be distributed. All betas operate within Apple's secure operating system sandbox and cannot access your device data without explicit permission. The beta is developed and maintained by Turing Software LLC.
Do in-app purchases or subscriptions cost real money during TestFlight beta testing?
No. In TestFlight, Apple connects all transactions to its free Sandbox environment. Any in-app purchase, pro feature tier, or subscription inside UTM Virtual Machines will display "[Environment: Sandbox]" and costs $0.00. Your Apple Account or credit card will never be billed for purchases made within a TestFlight beta build.
Does UTM Virtual Machines work on iOS 27 and the latest iPhone models?
Yes, UTM Virtual Machines is fully compatible with iOS 27 and iOS 26 across modern iPhones, including iPhone 18, 17, 16, 15, and 14 series. It supports modern iOS 27 capabilities including Siri AI, Dynamic Island, Lock Screen widgets, StandBy mode, and Apple Intelligence where applicable.
What should I do if the UTM Virtual Machines TestFlight beta says "This beta is full"?
Apple enforces a strict cap of 10,000 public testers per TestFlight app. Popular betas fill up quickly, but spots reopen regularly because Apple automatically purges inactive testers, and Turing Software LLC frequently clears inactive seats before dropping new beta builds. Tap the "Get Slot Alerts" button on this page to receive instant Email and Telegram alerts from CodeWing the moment an open slot is detected. You can also discover trending alternatives in the Productivity category.
Will installing the beta replace my current App Store version of UTM Virtual Machines, and will I lose my data?
Installing the TestFlight beta will replace the App Store version on your iPhone, but all your local app data, documents, logins, and configurations are safely preserved. If you ever want to switch back to the stable public release, you can simply redownload UTM Virtual Machines directly from the App Store at any time without losing your data.
How long does a TestFlight beta build last before it expires?
Each TestFlight build has a maximum lifespan of 90 days from the day the developer uploaded it to Apple. You can see the countdown days directly beneath UTM Virtual Machines's title in your TestFlight app. Developers regularly release new builds with improvements, which automatically resets the 90-day timer so your testing is uninterrupted.
How do I send feedback or report bugs for UTM Virtual Machines?
You can send feedback directly to Turing Software LLC by taking a screenshot while using UTM Virtual Machines and tapping "Share Beta Feedback", or by opening TestFlight, tapping UTM Virtual Machines, and selecting "Send Beta Feedback". You can include notes, screenshots, and system logs to help the developer fix issues before the official App Store launch.
