Collecting forks

Hello. Yesterday i had a target to found a place to collect cryptocurrencies.

Problems:

I have big balance and don't trust usually clients on my MacBook, because Mac OS is exploitable and hackers have a chance to steal money by RAT.
I want not start Virtual Machine to use this clients, because low-power of virtual machine can't check old blocks of forks. Not comfortable.
I want not to use hardware wallets(KeepKey, for example), because 1) Not all forks, that i like to collect, 2) Can be exploitable

In total, solution:

I will buy laptop, setup Debian or Ubuntu, or other desktop linux to use GUI clients. Clients i will transfer by usb, because web-surfing is dangerous(exploit pack intensive attacs). Network will work, but only for clients, not for web-surfing. It's good. And i need new Laptop, because i need good hardware, i want SSD.
