@paulgit I stopped using Fluid, for that very reason. Now my Single Site Browsers are supplied via Google Chrome using the Epichrome app to create them.
@konrad CleanMyMac is a reputable app. MacKeeper is the fox in the Mac henhouse. AVOID MACKEEPER!
I also discovered a strange error when trying to use various extensions in Photos app. Many photos couldn't be opened because they were the "wrong file type" or "couldn't be found." Googling the specific error revealed the culprit to be CleanMyMac 3! That app had been ripping out some iCloud photos & replacing them with things that worked OK in photos but not with any extensions.
So I threw out the entire 23.2 GB Photos Library & let the iCloud Photo Library repopulate the Mac's library. All OK now, photos that previously generated the error message are now editable in external apps. To prevent such behaviour in future, Photos app has been excluded from CleanMyMac's processes.
Using FruitJuice app to maximise MBA battery life. App wants me to use it on battery for 1 hr & 12 minutes. So I decided to do two Time Machine backups (one of 35 GB), one Carbon Copy Clone & a SuperDuper! clone while disconnected from power. Still need to use it for 28 minutes on battery.
@phoneboy So I tried it with iMazing, the app claimed to have done the task but the tone wasn't transferred. So I used iTunes but not via a sync. Just dragged & dropped onto the iPhone. However, I'm not running any betas. Just El Crapitan (10.11.5) & iOS 9.3.2.
Had a flat battery in the car today, called roadside assist. The fellow arrived about 40 minutes later & started the car instantly with one of these little beauties: http://www.carguru.com.au/jump-starters/9--the-super-mini-booster-is-the-smallest-and-most-powerful-jump-starter.html
Heard from my current ISP about problems with converting over to the NBN (National Broadband Network) - the FTTN technology isn't co-operating with the LLB (Last Little Bit) of copper phone line from the node to my place. Apparently he fix is to replace the LLB with an individual optic fibre cable plus a new smartbox to replace the modem.
