Well, unfortunately no -- there isn't an automatic fallback to a different B.E. like that. However, so long as you're on 10.3 or above you can select which boot environment to boot into from the boot menu. So if booting fails, just hit the reset button and choose a different boot environment to try again= =2E Cheers, Matthew --FHIOQvxp98XoQEumcVIi6MqmdVoHvtQsv-- --MwDMNuNIJg3T9PBTl7sf36xDR4MaA43qB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQJ8BAEBCgBmBQJZNJHSXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NTNBNjhCOTEzQTRFNkNGM0UxRTEzMjZC QjIzQUY1MThFMUE0MDEzAAoJELsjr1GOGkATVFUP+gNuCkOTcUDSak9BSNxZ3Vo+ 2qoCWlOUrpX6eJo4w1WJTlCkb/ALWR/118bYohgMkKn6j+ca8LLKvj7QOTF7C7vh mYob5Y0WpfqVVpSRBw46H8t2JgMsXyYizpu1MDRsbo43AqzwRy+im6UJkHwCRat5 Dct4AptBPCKW4F/BIeuCHRmnaiQtYJoqbGvNk5OfiFUv0IJyfJWRCsYUboYOAVkk aFkkYgeLeB/U1yJtVNt/DPiR7rjq71GLqCDUGgd/fuU8OtyoHO8D6uUXabxjw9Or QHxleFhg32ip40QetRzbEnmjtfESuObbY6hMWwh6aP5NrfFAypjFvkS4ji/rN4jR GLAmn5M1P3sA40SqRuKSqkmF/2XUAd6K9719jWzIYpgQE+a7EXQwnhOatqYS4Qv9 drxhLyRSDF91Nu4Nfh0B4n+koKNqfLnJR8F3ou7IK7hs7wsgdjT/JCROUeq5d3r2 8XwR3Pe7Gfb5QKXdoYOKSAW9pbI4Gky6HGtrEFs0xASRzoN7zeDiLOxzTfYfeHRM UxBgYErp+BgeK2tZW5qXbRaShmVO5P9W+mzUheKIu4Hw47V+K0V/RI2hmCpo64pn y4xJhEVg/qAXxzPjQAEXIFc9suKelKMfxqGUS8l2wQ2391nFCoTJIp+KkLkag0ws 1nb/hq9NrgoULNm/gG08 =hKNI -----END PGP SIGNATURE----- --MwDMNuNIJg3T9PBTl7sf36xDR4MaA43qB--
