Rectangle supports macOS v10.15+. The last version that is supported for macOS 10.13 and 10.14 is https://github.com/rxhanson/Rectangle/releases/tag/v0.73.
The [keyboard shortcuts](https://support.apple.com/guide/mac-help/what-are-those-symbols-shown-in-menus-cpmh0011/mac) are self explanatory, but the snap areas can use some explanation if you've never used them on Windows or other window management apps.
Drag a window to the edge of the screen. When the mouse cursor reaches the edge of the screen, you'll see a footprint that Rectangle will attempt to resize and move the window to when the click is released.
* Rectangle has additional window actions: move windows to each edge without resizing, maximize only the height of a window, almost maximizing a window.
* Next/prev screen thirds is replaced with explicitly first third, first two thirds, center third, last two thirds, and last third. Screen orientation is taken into account, as in first third will be left third on landscape and top third on portrait.
* You can however emulate Spectacle's third cycling using first and last third actions. So, if you repeatedly execute first third, it will cycle through thirds (first, center, last) and vice-versa with the last third.
Apple never released a public API for Spaces. Other apps that move windows between spaces use unsupported or undesirable ways to achieve this. If Apple decides to release a public API for it, I'll add it in.
By default iTerm2 will only resize in increments of character widths. There might be a setting inside iTerm2 to disable this, but you can change it with the following command.
If windows aren't resizing or moving as you expect, here's some initial steps to get to the bottom of it. Most issues of this type have been caused by other apps.
1. Make sure there are no other window manager applications running.
1. Make sure that the app whose windows are not behaving properly does not have any conflicting keyboard shortcuts.
1. Try using the menu items to execute a window action or changing the keyboard shortcut to something different so we can tell if it's a keyboard shortcut issue or not.
1. Enable debug logging, as per the instructions in the following section.
1. The logs are pretty straightforward. If your calculated rect and your resulting rect are identical, chances are that there is another application causing issues. Save your logs if needed to attach to an issue if you create one.
1. If you suspect there may be another application causing issues, try creating and logging in as a new macOS user.
#### Try resetting the macOS accessibility permissions for Rectangle:
```bash
tccutil reset All com.knollsoft.Rectangle
```
Or, this can be done with the following steps instead of the tccutil terminal command.
1. Close Rectangle if it's running
2. In System Settings -> Privacy & Security -> Accessibility, first disable Rectangle, then remove it with the minus button. (it's important to do both of those steps in that order)
3. Restart your mac.
4. Launch Rectangle and enable settings for it as prompted.
Upon launch, Rectangle will load a config file at `~/Library/Application Support/Rectangle/RectangleConfig.json` if it is present and will rename that file with a time/date stamp so that it isn't read on subsequent launches.
If you are using Rectangle v0.44+, you can also use the import/export button in the Preferences pane to share to your preferences and keyboard shortcuts across machines using a JSON file.
Rectangle can be uninstalled by quitting the app and moving it to the trash. You can remove the Rectangle defaults from your machine with the following terminal command:
Logic from Rectangle is used in the [Multitouch](https://multitouch.app) app. The [Rectangle Pro](https://rectangleapp.com/pro) app is entirely built on top of Rectangle. If you contribute significant code or localizations that get merged into Rectangle, you get a free license of Multitouch or Rectangle Pro. Contributors to Sparkle, MASShortcut, or Spectacle can also receive free Multitouch or Rectangle Pro licenses (just send me a direct message on [Gitter](https://gitter.im)).
If you would like to contribute to localization, all of the translations are held in the Main.strings per language. If you would like to add a localization but one doesn't currently exist and you don't know how to create one, create an issue and a translation file can be initialized.
The original repository for MASShortcut was archived, so Rectangle uses my [fork](https://github.com/rxhanson/MASShortcut). If you want to make any changes that involve MASShortcut, please make a pull request on my fork.
