Fix Home Folder Permissions

Here’s an AppleScript to help you regain control of your user home folder if permissions have been corrupted by performing certain actions such as installing software that doesn’t respect proper home folder permissions or by drag copying items when the current context for maintaining proper permissions is incorrect. Symptoms of this problem can range from not being able to see on the desktop items that are known to exist in the Desktop folder or not being able to move icons for desktop items to being unable to copy or move items inside the home folder.

The current user account must be an admin account when the script is used. If the account needing repair is not currently an admin account, you can use the Users & Groups prefpane to make it an admin account temporarily to run the script (providing, of course, that you have access to an admin account).


set username to do shell script "id -un"

do shell script "chown -R" & space & username & space & "~;chmod -RN ~;chmod -R o-w ~;chmod +a \"everyone deny delete\" ~/ ~/Desktop ~/Documents ~/Downloads ~/Library ~/Movies ~/Music ~/Pictures ~/Public ~/Sites;chmod +a \"" & username & space & "allow list,add_file,search,delete,add_subdirectory," &  "delete_child,readattr,writeattr,readextattr," &  "writeextattr,readsecurity,writesecurity,chown,file_inherit," & "directory_inherit\" ~/Public/Drop\\ Box" with administrator privileges

 

Login Items List

This is an AppleScript to give you control over your Mac user login items. They are the items displayed when you open System Preferences>Users & Groups>Login items (your user must be selected at the left in the Users & Groups prefpane).

Copy and paste the text on the right side in the text block below into an empty document window of Script Editor or AppleScript Editor on your Mac system. This script has worked since Mac OS X 10.3 Panther and I still use it in MacOS 10.12.5 Sierra.

Run the script.

Select one or more login items from the list and click OK.

Choose whether to reveal the login item in the Finder or to remove it from the current login items. (Tip: try revealing one or more login items first and if you don’t really want them removed after you test removing, just open login items in the Users & Groups System prefpane and drag them back in there!)

tell application "System Events"
activate
set loginItems to name of every login item
choose from list loginItems with multiple selections allowed
end tell
set theResult to result
if theResult is false then
tell me to quit
else
activate
if (count of items of theResult) is not 0 then
if (count of items of theResult) is 1 then
display dialog "What do you want to do with" & ¬
space & every item of theResult & "?" buttons ¬
{"Cancel", "Reveal it", "Remove it"}
else
display dialog "What do you want to do with
the selected login items?" buttons ¬
{"Cancel", "Reveal them", "Remove them"}
end if
if button returned of result contains "Remove" then
repeat with i in theResult
tell application "System Events"
delete (every login item whose name is (i as text))
end tell
end repeat
set this_user to (do shell script "id -un")
do shell script "killall -u" & space & this_user & space & "cfprefsd"
do shell script "killall -u root cfprefsd" with administrator privileges
else if button returned of result contains "Reveal" then
repeat with i in theResult
tell application "System Events"
set loginitempaths to (get the path of every login item)
repeat with loginitempath in loginitempaths
if loginitempath contains (i as text) then
set g to (loginitempath as text)
end if
end repeat
end tell
set actual_Path to POSIX file g
tell application "Finder"
activate
reveal (actual_Path as text)
end tell
end repeat
end if
end if
end if

Mallet Finger Injury – Two Years Later

When I sought medical attention for a mallet finger injury two years ago, what I learned was that I shouldn’t expect the affected finger ever to be exactly the same again. While that may be technically true, I was able to recover well enough that only very slight evidence of the injury remains, evidence that would only be detectable under very close examination. I’m convinced that the reason I recovered so well is that I took the initiative to build my treatment around my own design and method for making a custom splint.

The generic splint prescribed for me was too big and very difficult to keep fitted. It made the finger protrude enough past normal length that the finger was entirely unusable and the use of the entire hand was adversely affected.

To make a more effective, comfortable splint, I used a modeling material called InstaMorph, which can be heated to a temperature of 150° farenheit in water to allow it to become moldable. I then wrapped the warm pliable material around my finger and molded it to immobilize the affected joint only, and to support the fingertip while leaving it exposed, allowing me to use it for typing, etc. Of course it took a few tries, but once it felt right, I was able to wear it for the duration of the recommended splinted recovery time, both day and night, about 8 weeks. If my finger felt loose in the splint or I felt that it had accumulated too much dirt during the period, I simply discarded it and made another using more InstaMorph. I think I may have gone through 3 or 4 generations.

The goal of the design for the fingertip support point of the splint is that the joint be stretched slightly more backward than for a normal straight resting position for the joint. But it’s not necessary to bend the joint backwards far enough to make it uncomfortable. It’s possible to achieve this goal by realigning the fingertip support point while the InstaMorph is still somewhat pliable. That means removing the splint during the formation process and changing the shape slightly before it cools enough to become entirely rigid. Removing the splint before it becomes rigid during the formation process also ensures that the splint isn’t molded tightly enough to make it difficult to remove or to constrict the finger enough to adversely affect blood flow.

It’s important not to allow the affected joint to bend even once during the eight weeks, and wearing the splint, although removing it was easy, helped me achieve that goal. Along with exercises which consisted only of spreading and backward arching of all the fingers on the affected hand to the maximum possible position, the treatment has proved quite effective. After the eight weeks had passed, there was some residual feeling of weakness in the joint that lasted for a couple more months. However, during that time, I simply reapplied the splint temporarily whenever I became aware of the weak sensation in the joint, or when I considered that my activities might be increasing the likelihood of re-injury. The orthopedic surgeon who treated me was impressed enough to ask my permission to photograph the splint. The included photos that I took myself illustrate the overall design concept for the homemade splint.

 

 

Consolation2 – Log helper for Sierra

If you’ve missed the Console’s ability to access previous log entries in MacOS 10.12 – Sierra, Consolation2 can help. The interface, though actually quite simple, may appear somewhat intimidating to users who aren’t familiar with the many possibilities for examining log entries in MacOS. However, an extensive Help Book is available through the Help menu of the app, and contains lots of instructions and example scenarios for getting the most out of Consolation2.

Absird for Mac

Some 20 years ago, I became interested in Autostereograms. It was already at least several years after their popularity had peaked. Several years after working with them, I was able to port an old freeware Unix executable distributed by a gentlemen named Keith Goldfarb into Apple’s then free Xcode environment to create a graphical user interface for creating Autostereograms using a Mac. I haven’t upgraded it into the more complex Mac developer environment for use with the current Mac App Store, but if you’re comfortable tweaking GateKeeper to allow older or outsider apps to work on your Mac, you’re invited to play with Absird. A shortcut for getting around GateKeeper is available on my Really Quick page. Download from my Google Sites repository below.
