Yup, I used to install various versions of Mac OS in Virtualbox and the latest versions of Virtualbox always used to give some or the other errors. Even on their forums, they used to recommend to use older versions, mostly the version 4.2.x or 4.3.x something. Then everything used to work. But I had to keep trying among the older versions, too. Not all of them worked for the task. Only a specific version recommended by them or some old users. But I have got used to virtualbox so I would still prefer using it or recommend it to my friends. Might have to try VMware Player, but never felt the need to. Virtualbox gave some trouble at the start, but a little googling got me to learn more about it and I can handle it very well now. Feels home. But yup, gotta and have to try VMware Player now seeing the comments of other experts here.
I have been using VMware Player (Free) since 2011. Virtualbox lacks a feature to copy files from within the Virtual OS to main OS. Same doesn't apply to VMware Player
Not true, Virtual Box has the Shared Folder feature (although only if there are Virtual Box Guest Additions for that Guest OS). Otherwise, good old network shares work as well. With Guest Additions installed in the Guest, for some OS you can now even Drag and Drop files between Host and Guest.
yes, with few additions one can copy the files, but in case of VMware Player everything works out of the box.
From what I know the VMWare Easy OS Install automatically installs the VMWare Additions. In Virtual Box, there's no Easy Install and the VBox Additions need to be explicitly installed by hand.
For Windows 8.1/10 users starting with PRO edition there is also a free virtual machine available. Microsoft Hyper-V client, can be installed through the windows Feature menu. Also has its negative and positive, but maybe worth a try.
VMware better but only because I can use the virtual videocard inside my virtual machine. However, VirtualBox can be better in case of GNU/Linux because this supports many distros without problems. You can get a list of supported hosts and I don't see the new OpenSUSE 15 for example but they add support of the Ubuntu 18.04. If you need snapshots and you don't care about games or DirectX/OpenGL apps like I care, for an user without money or keys, VirtualBox is only way. VMware Player is not bad but it can't run more than one VM for example. Is somebody says Hyper-V? Okay I recommend use ESXI, QEMU, XEN or KVM, because this is a way, too. All this staff is free, you can try. ESXI, XEN or KVM allow play your games via PCI Passthrough in a VM with 98% of the host perfomance.
I have never had any problems with vmware... VirtualBox was buggy last time i tried it (was about 2 years ago... maybe things changed now ).
Vmware great software, with windows guest (also macos guest after unlock it) work very well, better than virtualbox. Virtualbox at my opinion is great with linux guest, most of its include addons and work very well.
