Q: the recent update for IPhoto (9.5.1) will not install on my Air. The error message comes back and says there is a problem with the App store. Please try later.  This has gone on for several days.  The update installed fine on my IMac.

Drag & drop the apps over your LAN from the iMac to the MBA.

Launch the Console application in any of the following ways:

☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.

☞ Open LaunchPad. Click Utilities, then Console in the icon grid.

Select

/var/log ▹ install.log

from the hierarchical list on the left. If you don't see that list, select

View ▹ Show Log List

from the menu bar. Then select the messages from the last installation or update attempt, starting from the time when you initiated it. If you're not sure when that was, start over and note the time. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).

If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.

When posting a log extract, be selective. Don't post more than is requested.

Please do not indiscriminately dump thousands of lines from the log into this discussion.
