Can't sign out of iCloud from iMac

[Alan Smith]

I cannot sign out of iCloud on my iMac via Apple - Preferences - iCloud.   I 
get info message “Your iCloud account couldn’t be removed at this time.  Turn 
off all iCloud services and try again".   The Keychain service cannot be 
unchecked, which I assume is the cause.

I signed in to icloud.com (a mistake??) via Safari and attempted to sign out of 
the Preferences account again, in case there was some interaction.  Then 
checked the box to log out of all browsers.  This logged me out of icloud.com 
but it no difference to my ability to sign out of the iCloud account via 
Preferences.

I am not signed in to iCloud from any iOS device.

Regards, 
Alan

Hi Bill,

Settings > General > About > Network  - Not Available (if you haven't got one) 
or Telstra Mobile (or whoever your mobile service provider is)
Cellular Data Number -  Unknown (if you haven't one)

Settings > Cellular Data  -Off  

The iPad cellular is only for Data - you can't make phone calls. (You could 
make & receive Skype calls BUT a strong WiFi connection is recommended).

Cheers,

Time Machine Backup

[Peter Crisp]

A couple of weeks ago I was using my MBP Retina 13" which I use quite rarely. I 
have an external drive attached (it contains my Photos and iTunes Libraries as 
well as quite a bit of other data) which is included in the backup.

At the time I wasn't doing anything much, just reviewing emails I think. I 
think I had used it the previous day after unmounting the external drive for 
some lap work. I reattached the external drive and it mounted typically without 
event.

Shortly after it set about a routing back up. After a long "Preparing your 
backup" it said, the backup is too large for your backup drive. 

The backup file currently is around 650GB made up of ~550GB on the external 
drive and ~100GB on the MBP. My backup drive is 1TB and has ~300GB+ of free 
space.

I suspect TM has had a fit and thinks it has to do a large backup of something, 
but hardly anything has changed. Just the emails I viewed and some browsing.

Do I blow away the sparesebundle (again) and reset the backup or is there 
another fix for this on going habit of TM?


Regards

Re: Malwarebytes, anti-malware for Mac

[Alex]

Hi Ronni

Thanks for this in-depth & informative info on this subject.

Unfortunately, in my dealings with the ATO I still have to use Java applets :(

Cheers,  Alex
