Hello,because I have to test my OS X app with an older Mac OS X version (to make sure it is still compatible) I would like to setup a VM with an older OS X Version (El Capitan or Yosemite) using Parallels desktop. In order to create the VM a need the installer package.I can see the older OS X versions in the Mac app store app in the list of my purchased apps, but when I click the downlaod button a message appears: "This version of OS X 10.10 cannot be installed on this computer" ...As far as I can see the Apple Developer Downloads at https://developer.apple.com/download/more/ doesn't include installer packages - just updates. Any ideas how to get an older OS X installer package ... for developing and testing? Best regards Frank

I have a problem with simple UITableView(Controller) with Style = plain and Seperator = default (all settings are default in the storyboard): As soon as I select "Optimize Interface for Mac" in the target General Tab (Deployment Info), the separators are not displayed anymore when the App is running under Mac catalyst (Big Sur 11.2). Any Ideas how to get the seperators back? Is this a bug or a feature?
