#Tips: How to delete backup from my mac

Hi Folks,

I had a lot of space in my Mac Book Pro dedicated to backups.

I want to share how to get this space back.

  1. Simply "turn off" Time Machine in its preference pane, under System Preferences.
  2. Turn it back on, or select "Back Up Now" in the title bar icon for TM, when you wish it to sync with your TC.

Alternatively, you can disable Local Snapshots as well, if you don't want to turn off Time Machine.

Enter this in Terminal:

sudo tmutil disablelocal

A guided tour of London not to be missed. Only 30 spots available, pre-registration required when you sign-in to the conference on Saturday.
Will last 2 hours approximately, covering the City of London and surrounding areas.


Below are a few hotel suggestions.
Please note London is a very large city and commuting may be time consuming. We suggest you choose a hotel either close to the conference venue (Acton, White City, Sheperd's Bush) or closer to the social even on Saturday night (Covent Garden, Soho, Charing Cross).
London Underground is expected to start a 24 hour service during the fall on week-ends. The announced date was September 12, but the recent Tube strikes have pushed this back and there is no official date for commencement of the 24 service yet.

Central London

These hotels are close to the social events on Saturday night, but expect around 30 minutes to get to the conference venue on Saturday:

Acton/White City

Closer to the conference venue. They are located in zone 2 of the London transporation zone, about 15-20 minutes from Central London
See you there!
