[NSButton state] must by used from the main thread

Hi there, XCode 9’s new main thread checker feature found the possible issue mentioned on the subject line. Indeed there is a background thread that check’s the state of an NSButton subclass, but I’m wondering if this is a real issue - I understand the problems with changing the UI from a backg

High Sierra

The developer downloads area has a button to download macOS High Sierra 10.13 17A365 Sep 25, 2017. Clicking the button takes me to an App Store macOS High Sierra Beta download. So how do I get the released version and not the beta? --Richard Charles _

Re: High Sierra

Likely you have a copy of the beta installer either on your boot drive or an attached periphery. Delete that copy (or move it to another disk and unmount it), then do ‘Command-R’ to refresh the App Store page. Best Phil @sqwarq > On 26 Sep 2017, at 19:50, Richard Charles wrote: > > The

Re: High Sierra

Fair enough. I’d seen (and had) the issue with an existing installer during the beta updates and figured it was the same. Glad you got it sorted! Best Phil @sqwarq > On 26 Sep 2017, at 20:25, Richard Charles wrote: > > >> On Sep 26, 2017, at 7:00 AM, sqwarqDev wrote: >> >> Likely you ha

Re: [NSButton state] must by used from the main thread

If you have an issue with one API reporting such an issue, write a radar, as I did for getting the application’s delegate when I encountered it. For a button’s state, however, there may be a better way to pass that value to a background thread, especially if the button should be setting a value
