Decide whether another window tool earns its place
Start with the controls already on your Mac. If they put your working document and reference window where you want them, keep that setup. Rectangle becomes a useful candidate when you repeatedly want a particular position and would prefer a dedicated shortcut for it.
Rectangle’s official site describes a free, open-source utility for moving and resizing windows with keyboard shortcuts or screen-edge snap areas. This review is based on documentation; no native Mac testing or comparative timings were performed.
Establish a no-install baseline
For macOS Tahoe 26, Apple documents dragging, green-button layouts, menu choices and keyboard shortcuts for tiling. With the intended window active, inspect Window → Move & Resize, or hold the pointer over its green button. Use the guide for your installed macOS version if its menus differ.
Try one ordinary task: a document beside a reference page, followed by one larger window for reading. These are proposed checks, not reported test results.
| Your task | Start here | A reason to consider Rectangle |
|---|---|---|
| Put two windows side by side | Try the system’s tiling controls | You prefer a dedicated assignment for the positions you use |
| Repeatedly enlarge and reposition one window | Try the system’s available arrangements | Your useful routine is easier to express with a small set of Rectangle actions |
| Fit unusually narrow windows | Check readability and the app’s size limits | Adding more positions will not remove the app’s own limits |
Judge the result with real content rather than empty windows. If either half makes a document uncomfortable to read, reconsider the arrangement before adding more shortcuts.
Install only after the baseline fails your task
The current Rectangle download specifies macOS 14 or later, checked on 23 October 2026. Use the official source and check the requirement again before installation; an old tutorial may describe a different release.
Rectangle’s permission troubleshooting covers its Accessibility access. Apple explains that this access must be granted deliberately and can be reviewed in System Settings → Privacy & Security → Accessibility. Review the app identity and follow your organization’s software policy on a managed Mac.
A small setup to try
Use this proposed routine to evaluate the app:
- Start with Left Half, Right Half and Maximize. Decide whether any other position is needed only after using those with your content.
- Open Rectangle’s Settings → Shortcuts and inspect those actions’ assignments. The maintained README describes the action fields in that tab. Avoid assigning a combination you need in the apps you use.
- Run a chosen action from Rectangle’s menu, then try its shortcut on the same window. Keep the action and window state consistent.
- Choose which tool should own dragging to the screen edge. Rectangle’s README documents disabling its drag snapping; a keyboard-focused trial can leave that behavior to the system.
- Return to your original task. Keep only the assignments you actually want to use.
In a hypothetical writing session, you might keep a document on the left and source material on the right. Choose keys and sizes for your own task, then see whether the arrangement removes a recurring interruption.
Match the symptom to the next check
Use the maintainer’s documented boundaries to choose a comparison. A different result narrows your next step; it does not prove a cause.
| What you notice | Next check | What the result does not establish |
|---|---|---|
| The menu works but the shortcut does not | Try a different assignment; inspect competing window utilities and the affected app’s shortcuts | Which particular app intercepted the original keys |
| A narrow layout overlaps another window | Try a larger layout and inspect the content’s readability | That another window manager can override the app’s minimum size |
| Neither menu nor shortcut moves the window | Compare another ordinary window, then review the documented permission and troubleshooting steps | That resetting permissions is necessarily the fix |
| You expected movement to another desktop or Space | Separate that requirement from movement between physical displays | That the free app supports switching a window between Spaces |
The README states that Rectangle cannot override an app’s minimum window size and does not move windows between desktops or Spaces. Its troubleshooting section recommends menu actions or a different binding when investigating shortcut problems. Follow those bounded checks before changing unrelated settings.
Keep the arrangement small
Keep Rectangle if the chosen actions make sense with the windows you actually use. If the built-in controls are already sufficient, or maintaining assignments creates another task, quit the utility and return to that baseline. No purchase or elaborate preset is required to make that decision.

Updated 23 October 2026: this review now centers on the built-in tiling baseline, a smaller proposed setup, and documented troubleshooting boundaries. It remains a researched overview.
