My employer provides me with a decent Windows desktop machine to perform my Software Development tasks. However, for a specific project I'm working on, a Mac would be better suited, providing benefits for both my employer and me (and we both agree on this).
They can't buy a Mac for me now, but they suggested me to use my personal MacBook.
What kind of compensation should I request from them in order to bring my laptop everyday? Even though they will probably expect me to bring it "for free".
There are several things to consider such as the risk of losing it, wear and tear, the burden of having to bring it everyday, etc.
It's important to note I'm excluding things like security, responsibilities boundaries, and other policy-related considerations from this question on purpose, since my question targets compensation specifically.
This situation is in the UK, if that changes anything.
UPDATE: Please, note that I'm not asking for advice about if I should do this or not. I'm asking this question because BYOD is quite a common practice nowadays in Software Development, and I think if you are bringing your personal computer, you should not do it for free.
UPDATE 2: I want to clarify I haven't agreed to anything with my employer. We agree a Mac would be better, and they suggested me to use my MacBook, but I haven't said yes. My apologies if my original question was not clear enough. I appreciate the amount of answers provided with different opinions.
