How to install macOS 10.12 Sierra on unsupported Mac hardware

by Joaquim Barbosa on Feb 23, 2017

With macOS Sierra, Apple dropped support for some of its hardware models for the first time in several years. Citing various incompatibilities and hardware deficiencies, they cut out a large swathe of machines from running Sierra. However, many Mac owners have questioned their motives, observing that some machines have made the cut whilst their more powerful contemporaries (such as the MacBook Pro) have mysteriously been left behind.

This led some to conclude that Apple is simply raising the bar to encourage hardware upgrades, and that there is often no incontrovertible hardware reason which dictates the unsupported machines. In many cases this turned out to be true, and with a few tweaks and amendments many of the “unsupported” machines have been brought back into the fold by a tool by dosdude1, called macOS Sierra Patcher. In this guide, we’ll walk you through how to use the tool to install macOS 10.12 Sierra on older Mac hardware, which claims not to support it. Read More

Possible downgrade to iOS 10.2 from iOS 10.2.1 for some users

by Joaquim Barbosa on Feb 20, 2017

Are you are stuck on iOS 10.2.1 or higher, having missed the iOS 10.2 signing window and therefore the Yalu jailbreak? If so, you may be in luck today, provided you have the correct setup. Early reports have come in that some devices are creating nonce collisions on iOS 10.3 b1, providing an indirect route back to iOS 10.2 through Prometheus.

For this clever workaround to come off, you must have a device which produces collisions, namely the iPhone 5s or (possibly, though not confirmed on iOS 10.3 b1), an iPad Air. If you do, you may be able to downgrade from iOS 10.2.1 to iOS 10.2 and jailbreak, by first downloading and installing iOS 10.3 beta 1, and then downgrading to iOS 10.2 using futurerestore.

AppSync beta released with iOS 10 support

by Joaquim Barbosa on Feb 14, 2017

One of the more common questions we’ve been getting here at iDB since the release of the Yalu jailbreak for iOS 10 is when AppSync Unified, from Karen Tsai (angelXwind), would be getting an update to make it compatible with the new jailbreak.

As you may be aware, many people got themselves into a respring loop of some description by installing AppSync soon after the Yalu jailbreaks came out. That should now have been fixed with this new beta version of AppSync Unified, available on Karen’s Cydia repository. Read More

 

Solution to 7-day signing for Yalu may be coming: avoid other methods!

by Joaquim Barbosa on Feb 9, 2017

Those of you who have jailbroken in recent times, with either yalu1011, yalu102, Home Depotor Pangu 9.2-9.3.3, can’t have failed to notice a new feature of these tools which jailbreakers never had to contend with before.

I’m not referring to the semi-untether here, but rather to the installing of a profile on your device which signs the jailbreak app for a certain amount of time. iOS 10 jailbreakers particularly have felt the irritation of this limitation, but all that may be about to change, based on some tentative words from Cydia creator Jay Freeman (Saurik).

At the same time, other workarounds for the seven-day signing limit have started surfacing; these are almost all a bad idea, and should be avoided.

Cydia 1.1.28 exits beta: purchases now enabled on iOS 10

by Joaquim Barbosa on Feb 5, 2017

Since the release of yalu102 for iOS 10.0-10.2, users of the newest jailbreak have been unable to make new purchases on the Cydia store. This is completely normal behaviour; Saurik disables purchases on new firmware versions until both Cydia and the jailbreak reach a level of stability. The reason for this is to prevent complaints, refunds, and device problems brought about by the purchase and use of incompatible tweaks.

Today Cydia 1.1.28 exited beta, and that, in combination with the relative stability of the later yalu102 beta builds, seems to have satisfied Saurik as to the platform’s readiness to receive paid transactions.

Support for iPhone 7 and iPhone 7 Plus still coming to Yalu jailbreak

by Joaquim Barbosa on Feb 4, 2017

Since our most recent post on the subject of Luca Todesco’s Yalu jailbreaks for iOS 10, we have been receiving queries from our readers about the status of the iPhone 7 and iPhone 7 Plus. Although the two flagship devices were supported on the first version of the tool, which was for iOS 10(.1(.1)), they were omitted from the follow-up tool for iOS 10.0-10.2.

This has caused some to doubt whether these devices will ever see a stable build of the jailbreak, and whether they have been forgotten about. Fortunately, these worries are groundless; support for the iPhone 7 and iPhone 7 Plus is still very much planned. Read More
