Ballistics software Mac compatible... ChairGun is gone.

Try this site for a full set of free airgun ballistic software, very similar to Chairgun.

Thanks for these chair gun alternatives. MERO looks like what I need but my MacBook Air running Monterey ver 12.6.6 won't open the .pkg file that I downloaded; I get - “mero_184_arm64.pkg” cannot be opened because it is from an unidentified developer. can't verify it is free of malware. Any thoughts on opening the files will be appreciated...thanks
