Clamshell goes to iPhone and iPad! This is an iOS version of the Clamshell app. It provides monitoring states of all your Macs from your iPhones and iPads that are signed in to the same iCloud account.

More statuses will come in the year. No data is shared with third-party providers. Clamshell is not using any external servers but only Apple's iCloud servers. You're in full control of your data!

So far it is working great! Granted it’s only been 2 days - but here’s hoping there are no bugs lying in wait…. **Developer response:** Thank you! Sadly, there is no software without bugs, but feel free to report any to support. ### 5/5 — This saved my day *2024-12-28* New monitor, much appreciated. Found this on reddit. So demure, so helpful **Developer response:** Thank you! ### 5/5 — High Hopes *2024-11-07* With External Displays, the MacBook sleeps for only a few seconds before bringing all the external displays back with the login prompt. I have the same behavior occur with DisplayLink, which has a similar sleep displays in clamshell mode feature. Wish I had better news to report. **Developer response:** It seems like we don't have any useful data to work with right now. If you're having trouble, please reach out to our support team. They'd love to help you out and would appreciate any additional information you can provide: 1. What are the names of the external display models? 2. How are the external displays connected to your MacBook? 3. What modes of Clamshell are you using? 4. If you have any Clamshell logs, please share them as well. ### 1/5 — Does not run *2024-07-21* Downloaded and installed on M3 Macbook Pro running Sonoma Version 14.5 (23F79). App will not open. **Developer response:** It runs in the menu bar. No window opens on the start. ### 5/5 — Brilliant... *2024-02-18* I've been exploring ways to make this happen: close the lid on my macbook, and have my external monitor also sleep. This is (finally) a way to (simply!) do that. so for me, an essential app.... **Developer response:** Thank you! ## Frequently asked questions about Clamshell ### What devices does Clamshell support?
