  1. Check your coverage area to make sure you're in an area with cellular network coverage.
    • If you can't connect to a cellular network, make sure cellular data is on in Settings > Cellular.

  2. Restart your iPhone or iPad.
  3. Check for a Carrier Settings Update.
  4. Remove the SIM card then reinsert it. If the SIM card is damaged, worn, or bent, or doesn't fit in the SIM tray, contact your carrier.
  5. Try another location. If possible, see if other devices are able to connect to your carrier's network in that location. 
  6. Contact your carrier to:

    • Make sure there are no outages in your area.
    • Check that your device is not blocked from receiving cellular services and set up with the right data plan.

OSX Yosemite Batch File/Folder Renaming

Posted in Apple Mac OS

New to Yosemite is the ability to batch rename files/folders. Quite handy for a folder full of pictures, audio files, documents, etc. The process is fairly simple, just select the group of files that you want to rename, [Control] + [Click] on the group of selected files, then in the contextual menu choose “Rename XX Items…”. You’ll then be prompted by a small drop-down selector that will allow you to do any of the following:

_Completely rename a group of files, and add a sequential number
_Add text to the beginning of all selected file names
_Add text to the end of all selected file names
_Perform text “find and replace"

This can be a very useful tool in your daily file organization and maintenance.

Posted in Apple Mac OS

On May 18th, Dropbox will no longer support the OS X Tiger 10.4 and OS X Leopard 10.5 operating systems. 

Since one or more of your computers is running the Dropbox desktop application (client) on an older operating system (OS X Tiger 10.4 or OS X Leopard 10.5), you'll need to update to OS X Snow Leopard 10.6 or later to continue to access your files through the Dropbox desktop application.

If you don't want to or can't update your operating system, your files will still be available through the Dropbox website. However, on May 18th you'll be signed out of your Dropbox application on your computer and the Dropbox desktop application will no longer be accessible.
