Since updating to LR 2015.7 and Macs OS X Sierra, the badge numbers in the grid view are no longer visible no matter what view I choose (expanded, compact, etc.). For good measure I recalibrated my display and that doesn't make a difference. This is not a problem for 2015.7 using other machines running El Capitan and Yosemite.
Yep, me too. Just updated to Sierra and the large grey Index / Badge number is now gone in latest version of LR. Obviously a bug that needs sorting. A bit annoying for the time being though when working with large wedding galleries and wanting to know numbers
Compared to Aperture (and like a lot of the Lightroom UI compared to Aperture), badge numbers have always been almost impossible to see. How about really fixing this so they are useful?
Since updating to macOS Sierra (actually, beta testing it all summer), Index Numbers have disappeared in compact cells in Grid view. This makes it unnecessarily hard to keep my place when jumping between folders when culling, and creates other organizational problems. I filed a Feedback Assistant bug report with Apple in July, but they don't appear to have fixed it.
Since updating to macOS Serra and LR 6.0 to LR 6.7 After editing about 1/2 hr in the Develop module, LR hang (with loading.. message) must reboot iMac and this problem keep repeating.
This sounds like a different issue than is being discussed here. If the whole system is locking up, that could be a bad driver (try disabling Graphics Processor under Preferences > Performance. It could also indicate a hardware failure (failing hard disk, bad RAM, or Graphics Card). It could also indicate a damaged OS.
I just noticed this issue when culling my first wedding after upgrading to Sierra. This is seriously messing with my flow. I realize that I can switch to expanded cells and see the index numbers, but compact cells is my preference. Please address soon!
