We are going to release a Mac version soon! Stay tuned!
Currently, Octoparse supports running on a Windows environment. If you are using a non-Windows machine such as Mac or Linux, Here’re some suggestions for you to run Octoparse for data collection.
1. Use a virtual machine
A virtual machine can be very useful when you need to run apps that will only run on another operating system. It allows you to run 2 or more operating systems on one physical machine. But please note that the virtual machine also shares your computer memory and when your system space is small, the VM may run unsmoothly.
If you think using a virtual machine is a decent solution, here are some options for your reference:
· Oracle VM Virtualbox 
- Free and supports a wide selection of pre-built virtual machines to download and use at no cost.
· Parallels Desktop 13 - A paid tool exclusive for running Windows on Mac. A few of the elegant things that Parallels can do is make Windows alerts appear in the Mac notification center, and operate a unified clipboard.
· VMware Fusion – A paid tool offers a very comprehensive selection of virtualization products. Similar to Parallel Desktop 13.
2. Use remote desktop connection
Remote Desktop Connection lets you remotely control a Windows machine from a PC or Mac. Remote desktops are based on the use of Microsoft terminal servers. You need to establish a connection to one or more servers and run the applications directly. Compared to using a virtual machine, using remote desktop would be simpler to set up. You can download the Microsoft Remote Desktop client for Mac from the Mac App Store.
