Designing a custom symbol or image lets you communicate unique details that help people use your app repurposing a system-defined image can cause confusion. For guidance, see Accessibility > Copy and Images.Дesign a custom symbol or image if you canвЂ™t find a system-defined one that meets your needs.

Alternative text labels - or accessibility descriptions - arenвЂ™t visible, but they let VoiceOver audibly describe whatвЂ™s onscreen, making navigation easier for people with visual disabilities. Supply alternative text labels for all meaningful images. Although the вЂњleft-facing triangleвЂќ image looks the same as the вЂњgo leftвЂќ image, using it in a navigation control might be confusing if the appearance of the triangle changes in the future. For example, in a control that lets people navigate to the left, it makes sense to use the вЂњgo leftвЂќ image. When you choose an image for its meaning, your app can remain visually consistent with the system even if the appearance of the image changes. Use each system-defined image according to its meaning - not its appearance. In some cases, a symbol might not have the same size or alignment as the image it replaces, so itвЂ™s important to check your layout. For example, hovering the Dropbox menu bar item shows 'Dropbox ' under AXHelp, and hovering Little Snitch shows 'Little Snitch Agent' under AXTitle.IMPORTANT By default, the system APIs return SF symbols configured as 13 pt, large scale, and medium weight. Hover over the item and the pane may show you enough information for you to determine what it is. You can use the Accessibility Inspector, accessible from Xcode в†’ Open Developer Tool в†’ Accessibility Inspector. Try restarting SystemUIServer and watching to see if you can notice the hanging app: killall -HUP SystemUIServer Check Activity Monitor for any apps that show Not Responding for their process.Check the log in Console.app (/Applications/Utilities/), looking for any apps which you know have menu bar items present, or any references to SystemUIServer.This can be caused by missing/corrupt menu items that hook into the SystemUIServer such as first-party menu items or apps like iStat Menus which integrate into the SystemUIServer (you can usually distinguish these because you can вЊ-drag them between other apps' menu bar items.
