```finch vm init``` ```finch vm start``` Finch virtual machine failed to start. Symbol not found

[Azunyan1111]

Describe the bug I am unable to start a VM on my Macbook pro (10.15.4).

When I run finch vm init, I get the logs listed at the bottom, and finch vm start gives the same message.

These prevent me from running finch.

Steps to reproduce

1. install Finch from using Finch-v0.1.0-x86_64.pkg
2. run the finch vm init command and log at the bottom
3. run finch vm start command and log at bottom

Seems like some dependencies were built on higher os version, which may result in the failure: /Applications/Finch/lima/bin/qemu-system-x86_64 (which was built for Mac OS X 11.0) We will try some lower version os and reproduce the issue.

[Azunyan1111]

@KevinLiAWS Thanks for the reply. I replaced qemu-system-x86_64 with a binary file that works with 10.15 as you suggested and it worked!

Not a nice do it,but I'll leave a note on what I did to fix it

$ brew install qemu
omit...

$ brew list qemu # find qemu path
/usr/local/Cellar/qemu/7.1.0/bin/elf2dmp
....

$ ls /usr/local/Cellar/qemu/7.1.0/bin/qemu-system-x86_64 # qemu-system-x86_64 is here
/usr/local/Cellar/qemu/7.1.0/bin/qemu-system-x86_64

$ cd /Applications/Finch/lima/bin
$ mv qemu-system-x86_64 ~/ # backup
$ cp /usr/local/Cellar/qemu/7.1.0/bin/qemu-system-x86_64 . # replace

@Azunyan1111 Thank you so much for testing it out. It verified that the binaries have to be compatable with the supported os version to fix this issue. I will keep you updated for the fix.

This issue got fixed in the new release v0.1.1. Now 10.15(intel chip) is able to run finch.
