Apple’s recent macOS 10.13.4 update is causing some havoc among people using screen extenders like Duet Display and Air Display, as well as USB DisplayLink-connected monitors. AppleInsider – Frontpage News
Users of popular Mac desktop extension app Duet Display are being advised not to update to macOS 10.13.4, due to “critical bugs” that prevent the software from communicating with connected iOS devices used as extra displays.
When installed on a Mac and an iPad (or iPhone) and the two devices are connected using a Lightning cable or 30-pin connector, Duet allows users to extend their macOS desktop space on the Retina display of the iOS device. However, unspecified changes in the latest update to macOS High Sierra, released by Apple yesterday, causes the Duet client app to hang, and users are being advised to hold back from upgrading, at least for now.
The critical issue was highlighted by Duet’s ex-Apple developers in a blog post on the Duet support site, quoted from below.
Unfortunately, the upcoming version of macOS has several critical bugs that make it impossible for Duet to work properly. We have alerted Apple to their issue, but we have not received a concrete timeline on a fix. These features continue to work as expected in 10.13.3.
Duet’s developers are recommending that users contact Apple through the company’s online bug reporting form to get the issue prioritized. In the meantime, the developers are “actively looking” into workarounds to reinstate Duet’s functionality in macOS 10.13.4.
Duet Display is priced at $19.99 in the App Store, and unlocking the Pro features to turn the iPad Pro into a drawing tablet costs an additional $19.99 per year through an in-app subscription. Duet Display is available from the App Store. [Direct Link]
The developers of the Duet Display app that allows the use of an iPad as an second screen for a Mac have released an update to the Pro in-app subscription, allowing for better color quality, better pressure curve customization, and more. AppleInsider – Frontpage News
