1. Why are there two downloadable versions of Horos? What’s the difference? Which one should I download?
Horos is continuously evolving. New features, enhancements, and bug fixes are always up and coming. The two versions available for download include the “Release Candidate” and the “Latest Version”.
The Release Candidate includes the next step in Horos evolution. It has all the new fixes, advanced improvements, and milestones. However, the biggest difference between it and the Latest Version is that the Release Candidate is available to the community to provide feedback to us. Remember, Horos is an open source project and it would not be the success it is today without your valuable input. So, give the Release Candidate a try if you are open to providing us with constructive criticism about how we can overall improve Horos for the community.
The Latest Version is a version that has officially been used and test driven by end users in the Horos community.
2. Does Horos run on Windows or Linux?
No, Horos currently only runs on a Mac computer with macOS 10.11 or later.
However, Purview Image does support Windows, Linux and even iOS/Android devices.
3. What configuration of hardware is required to run on a Mac?
The short answer? All Mac computers that can run macOS 10.11 or later. However, viewing medical images is memory intensive and can also require considerable CPU and GPU processing power. Our recommendation is to use Mac computers with i5 processors, 16GB RAM, and equipped with a discrete GPU or Intel Iris.
4. What MacOS should I run for each version?
MacOS 10.11 or later.
5. How do I stay updated on recent developments? 3
Horos features a notification system that will alert you when new updates are available. 4
6. Can I store my images in iCloud?
We recommend that you don’t. It’s risky to store your images in iCloud. If you have more than one Mac computer logged into iCloud using the same Apple ID, and Horos is running on these computers, it’s probable that you will see your database getting corrupted. Even worse, your images could get overwritten by other images.
There is a software designed to work alongside Horos to provide storage, sharing, and reporting called Purview Lite. You can access your images from any device, at any time, and you can also easily share your images securely through the cloud with other physicians or patients.
