How to remove purgeable files in macOS and reclaim free space
After deleting Files on a macOS SSD, free space is not directly available.
This behaviour is intended to save the read/write cycles of the SSD.
Unless you begin writing new files, which require the purgeable space, macOS begins to free up space.
Sometimes you want to install Applications, which fails due to not enough space, although you actually removed enough files.
With this Terminal Command you can remove the purgeable space
What is does, is generating one big file as big as the purgeable space, wait few seconds and deleting it again, so that the OS has to really clear it.

Open Terminal and paste the following one liner and hit Enter
gb="$(df -h / | grep /dev/ | awk '{print $4}' | sed 's/[^0-9]//g')"; echo gb=$gb; dd if=/dev/zero of=/tmp/gb_filename bs=1024 count=${gb}000000; sync; sleep 100; rm -f /tmp/gb_filename
After Unpacking the zip Files of my Flickr Data Export, I found the Metadata in json files and Photos without the Original Modification Date.
Using exiftool on mac I managed to Re-Import the EXIF Data and Adjust the Date to the Date of the Photo taken
1. Install exiftool command
https://sourceforge.net/projects/exiftool
2. adjust the folder path in the dir variable containing your unpacked flickr export data
3. Run This One Line Command in Terminal and it will pick the matching id from the json file and apply to the related photo:
dir="/Users/islam/Downloads/my_flickr_export"; for json in $(find "${dir}" -name "*.json" -type f); do id="$(basename "${json}" | cut -d. -f1 | cut -d_ -f2)"; photo="$(find "${dir}" -name "*${id}*" -not -name "*.json" -type f)"; exiftool -m -d "%Y-%m-%d %H:%M:%S" -tagsfromfile "${json}" "-Keywords<tags" "-Subject<tags" "-Caption-Abstract<name" "-ImageDescription<description" "-DateTimeOriginal<date_taken" -ext "*" -overwrite_original -progress "-filemodifydate<date_taken" "-filecreatedate<date_taken" --ext json "${photo}"; done
Finally, you can delete json Files
dir="/Users/islam/Downloads/my_flickr_export"; find "${dir}" -name "*.json" -type f -delete
I have similar working solution for Google Photos takeout too.
