This repository includes scripts for deleting all or many iMessages with one click.
Because succeeding generations of OSX reduced the functionality of Message's AppleScript interface, the version for Ventura and later deletes 10 conversations at a time rather than all. You can edit the script to change the fixed number.

It's not for faint of heart, but you can find all the files you need here in LisaEM.zip.

This script ImportPhotoFolders enables you to upload multiple folders into Apple Photos where each directory becomes an album.
The repository includes the script Set Photo Title to Filename, which sets the title of each selected photo to its filename.

This program exports any number of your OS X Apple Photos albums with one click.
Each album turns into a folder with photos that are numbered so that they are in the correct order.
Exporting a folder exports all its albums and subfolders. Photos folders turn into Finder folders, nested hierarchically.
You can select the top level albums and folders to export.
Requires the free Photos Utility Suite to be installed.

This Python program uploads multiple directories to Google Photos into new albums with the same names as the directories.
Clone GitLab repository GPhotos Upload Albums.

Google Photos organizes photos in albums by date, and there is no option for organizing photos alphabetically by file name. If your have a file directory that corresponds to a photo album where photos are numbered or alphabetized to represent their order in the album, then uploading the directory to Google Photos will disorder the photos.
mass-change-photo-dates.sh processes one or more folders at a time, and changes the timestamps so that the increasing order of time matches the the alphabetic order of file names. The script handles the oddities of how Google Photo determines timestamps and timezones, which is no at all what you might expect!
After processing, upload the contents of your folder to Google Photos using the gphotos_upload_albums script above. Recreate the album from the "last uploaded" set of photos, and set the album sort to "date" rather than "upload order".
Requires installation of the free program exiftool.

An old macbook I was using as a file and iTunes server would lose its wifi connection from time to time, and fail to reconnect automatically.
I wrote this little script to test the wifi every hour, and if it was not connected to my network, to reconnect. In this script, replace "NETWORK" with the name of your network, and "PASSWORD" with the network password.
```
#!/bin/bash
if [[ $(/usr/sbin/networksetup -getairportnetwork en0) != *" NETWORK" ]]; then
    /usr/sbin/networksetup -setairportnetwork en0 NETWORK PASSWORD
fi
```
Give the script a name, say /Users/ME/bin/fixwifi. Then update your crontab to run it hourly:
```
echo '0 * * * * /Users/ME/bin/fixwifi' | crontab
  
```
