Creative Cloud prevents my MacBook Air from sleeping. I am surprised no one elese is raising this as a major bug. The only way my MacxBook will now sleep is if I quit Creative Cloud.
If I list programmes preventing sleep in Activity Monitor, Creative clioud is always there. I went through a long process of discontecting all peripherals, turning off BlueTooth and WiFi, quiting all applications except core Apple ones and then gradually adding back all these items to make my discovery.
I am surpised that more people are not reporting this.
